Question From the Audience

Question From the Audience:

When Arthur Jones tested people throughout their range of motion after the development of MEDX he found that only about 20% of the people who exercised through a partial range of motion had gains through the full range of motion. Therefore, the argument for static exercise as an ultimate exercise is moot for the general population. Why the revision of static exercise? What do you know that I do not?

To begin with, it should be noted that the RenEx position on TSC exercise is not conclusive with respect to a stand-alone program for total body fitness. We have some ideas about what we believe is possible but at this stage we do not suggest that TSC should replace dynamic exercise except in those cases for whom TSC is the only possible option.

We have been very impressed with the results of TSC as viable technique that can be used in addition to dynamic, as a rehabilitation technique, as a pre-exhaust mechanism, and even (for some) in whole body workouts but we still have ways to go before declaring any broad generalizations.

What we do know is that TSC is very safe and very productive. Our collective experience in the RenEx team is that it is the most promising development in the field of strength exercise to date. TSC permits us to instruct exercises that ordinarily rank as unsafe. It helps us teach proper protocol. It helps subjects connect their neurologically inefficient muscles to their minds so that they can recognize which structures they are attending to. It helps circumvent joint debilities and derangements. And, it can exist in its own right as a powerful independent technique for muscular stimulation.

The type S and G curves that you reference from MedX have been the subject of much debate and consideration. It may very well be true that specific vs general adaptations can occur from one subject to the next when considering aspects of exercise such as range of motion. Exercising in a partial range may indeed promote strength increases only in the trained ROMs in some while presenting increases in the full ROMs in others. But before we concede this it is important to consider the methods used to arrive the conclusions that MedX did.

Because the standards of loading with Medx are borrowed essentially from the nautilus model, it is our contention that the gauge for set volume was not only low but also highly inconsistent. At the suggested 4/4 cadence (though better than 2/4), regardless of range of motion, the subject is moving too quickly to expose the structures to the kind of loading that could indeed reflect adaptive variations due to ROM. Stated simply, a 4/4 protocol is not remotely controlled enough to conduct such an experiment validly.

In TSC exercise, the loading sequence and timing is strictly enforced with a “no escape” modality that encourages a continuous and effective loading of the structures. The effect is so potent that our contention is that eventually, regardless of position, the majority of the structure will become involved, if not fatigued and inroaded. This can be easily felt during an advanced TSC workout.

Of course, such an advanced workout requires significant experience and practice and is remarkably uncomfortable, even to the extent of promoting sensations of deep muscular damage during the performance of the set. But the effect of such effort is an unmistakable depth of loading that leaves little doubt as to the totality of work performed by the target structures.


RenEx Pulldown

In my own practice, I have worked with feeble subjects that couldn’t perform dynamic exercise (pulldown) because of pain in the elbows as well as overall weakness. But after one year of consistent TSC pullover/pulldown exercise, the subject was able to adapt to full range dynamic PD with zero pain and a rapid progression to resistance values that would ordinarily have taken many more weeks, by my experience.  In the case of one male who couldn’t perform 6 repetitions with #60 in his first attempts on the dynamic machine, i was able to progress him to #135 over the course of 4 weeks after having done only static exercise prior to this for 9 months. This is a remarkable achievement and directly flies in the face of the type S and G theory.

RenEx TSC Pullover/Pulldown

RenEx TSC Pullover/Pulldown

Of course, this subject could have been considered a type G subject but we are seeing this sort of thing in larger numbers and across a broader and broader spectrum of subjects making it far more likely that even S type subjects are going to respond the same way.

RenEx Trunk Extension

RenEx Trunk Extension

In a related ongoing anecdotal experiment, I have started many of my clients on the Renex Trunk Extension after having worked on the MedX lumbar machine for (in some cases) years. The maximum range of motion in the MedX is 72 degrees although in Renex protocol we never have gone past 50 degrees because of compression force concerns in the flexed position. The RenEx machine can provide a range of motion of over 135 degrees. Most of my subjects have easily been able to adapt to the increased range of the new machine. In many cases, subjects are achieving 120, 125 and even 130 degrees of range with ever increasing weights. Of course,72 degree medx lum in the beginning of such a change I am deliberately being conservative with range of motion and even more so with weights but it hasn’t taken some clients long to achieve comparable statistics in the new machine and with a dramatic new range of motion to boot.

With all of this said, there is one more thing to consider. It is very challenging to distinguish between the effects of skill acquisition and strength, particularly early in a program. In fact, that line is most blurred during a critical period of growth during intermediate levels of exercise in a give routine. A subject improves in a relatively non-linear way in terms of his capacity for ROM, total resistance, and the demonstration of endurance within a given protocol. What improves over a given time frame includes many aspects including motivation, strength, skill, nervous system communication, cardiorespiratory improvements and many more.

After enough time has passed within a given paradigm of exercise, the subject will “top out” aspects such as skill, and neurological learning. Even motivation will reach a pinnacle. Eventually, the only thing that will permit any demonstrable statistical improvement is what we might call strength.

Since it may take a considerable amount of time to achieve  the state of increasing “strength”, perhaps the assignation of type S and G curves is moot.  What if a type S subject just needs a handful of brief workouts in his previously untrained ROM to then demonstrate equal strength in that ROM a very short time later?

In the end, this and other questions might be better answered as we delve deeper into TSC and the future of exercise.

Can you describe in more detail the “type S and G curves”? I think this is a huge question that I’ve been wondering about. I’d love to tell clients with complete confidence that functional strength can be achieved with static exercise alone. Based on experiences and testimony it appears to be true. I’ve found when working through partial range of motion due to pain/injury that the pain area can be diminished over time until a fuller range is established. Does this indicate that the entire musculature of that joint is being strengthened regardless of the range of motion?

avatar Trace April 11, 2013 at 1:54 pm

Thanks, Josh, for the Arthur Jones Collection link – it helped clarify the points made by Gus. The comparisons between a Type G and S subject may be invalid based on other factors. It’s very interesting how time spent doing TSC inevitably improves one’s ability on a given dynamic exercise. When someone is stalling on a shoulder press, for example. So far it’s worked every time. This is great stuff.


avatar Gus Diamantopoulos April 11, 2013 at 12:17 am


The idea is that some people are put together in a way that permits them to get stronger throughout the entire range of motion in a given exercise regardless of if they have only exercised a partial range in that exercise. And that other people will only get stronger in the particular range of motion that they used in the exercise.

Again, all i can do is tell you that i personally believe that TSC exercise can render this concept not accurate or perhaps oversimplified. At the very least, I can state that i’ve experienced what you have; that people are able to substantially reduce their pain, increase their range of motion, and ultimately increase strength throughout a range of motion that exceeds their static training ROM.

Ken’s theory about TSC (that if worked with enough effort, the entire musculature must become involved regardless of position) has always made visceral sense to me. And it seems to be substantiated in innumerable ways in my practice with clients.

I personally have great confidence in suggesting to my clientele that TSC can promote overall improvements in strength (or as you call it, functional strength).

Fortunately i have been doing TSC for many years now and have seen some amazing success stories so the concept is not nearly so far a reach, intellectually.

For many reading here, this may all seem a little far fetched but as i’ve said many times before, all it takes is one combination set of static pullover/pulldown to experience what might be possible with this type of isometric exercise.

Time will tell us much as we move forward, i am sure….

I used to think general response was tied to neurological efficency in being able to contract a higher percentage of you fibers at any given time. And was a trait of some trainees and not others. You’ve given me some other ways of looking at it. Thanks Josh

“In the end, this and other questions might be better answered as we delve deeper into TSC and the future of exercise.”

I’m looking forward to these questions and answers as RenX learns more and more regarding TSC. TSC is a protocol with many different sides to it.

I have read so many articles stating that leg extensions are a dangerous exercise.It is hard for me to believe this as experts like Arthur Jones,Ken Hutchins and Jim flanagan have used these exercises to rehab people after surgery or after getting an injury.I would think that with all the research these three men have done they would know a heck of alot more than many of these so called experts that like to pretend they know more than they really do.Am I looking at this wrong or our there many trainers out there that really know nothing.Thanks

Hi Gus,

“To instruct exercises that ordinarily rank as unsafe”, this would be a great benefit for many people. Do you think that TSC could also be used as a method to help people learn how to deeply inorad. I am often asked how to get people to increase their effort when exercising could I suggest using TSC.


avatar Gus Diamantopoulos April 12, 2013 at 6:22 pm

Hi Steven,

Yes, TSC works very well in a workout that includes dynamic as well as static exercises. Blending TSC exercises with any combination of dynamic exercises can help any subject improve his concentration and increase effort.

In dynamic exercise sometimes we can become wired and stressed. A TSC set can serve to calm us down and blot out the noise. It can literally teach us to channel our effort to the most important aspect of strength exercise which is to maximally contract the target structures and to eventually inroad them.

TSC promotes stillness which is an often overlooked necessity in a well-performed workout. This naturally leads to better focus and a much higher likelihood that we can override the pain that accompanies high effort muscular work.

Perhaps you will share more about the both of your workout experiences.



avatar Bradley warlow April 15, 2013 at 6:19 am

It could just be a simple case of the assumed objective vs. The real objective with the type s subjects falling into the former and the type g subjects the latter.
Also perhaps as far as skill acquisition is concerned, in the field of sports science there are what are known as closed skills and open skills. A closed skill involves performing a single deliberate movement that doesnt change much if at all , such as a golf swing or dart throw, where as to attain open skill involves the ability to understand the ‘feel’ of the game so that a player can adapt to any situation even if they have never used that technique in practice.
@all does anyone think there is some relationship between this and skill in exercise?


avatar Bradley April 15, 2013 at 11:49 am

Of course, such an advanced workout requires significant experience and practice and is remarkably uncomfortable, even to the extent of promoting sensations of deep muscular damage during the performance of the set.
Gus- do you know if this is actually a good thing? or are you guys just experinementing with rapid inroading to the point where it may actually be dangerous?


avatar Gus Diamantopoulos April 18, 2013 at 7:19 pm

The beauty of ffeedback-based TSC is that it gives us “eyes” that we never had before. We can immediately detect risk factors and keep clear of danger.

What we know thus far is that if one follows the protocol, TSC is safe even at the advanced levels.

We also know (for a fact) that performing sets of shorter duration than our prescribed protocol and with too rapid an inroading process can cause injury.

No different than choosing too heavy a load and attempting a one rep max.

Reviewing the photos of the RenEx seminar I see the elderly and the emaciated. Was there anybody present that would represent the average lifter?

Is the John Hopkins study underway now or will your machines gather dust for another year before the study begins?


avatar Joshua Trentine April 18, 2013 at 7:40 pm

Dear db144,

It must make you feel particularly manly to insult and disrespect people in photographs attending a learning and educational seminar. And to single out folks for their age and their body type takes a real special kind of classless, oafish bully.

You should be flat out ashamed of yourself.


avatar Steven Turner April 17, 2013 at 9:15 pm

Hi Mike L,

I don’t want to speak for the RenEX team but I have found that it is not the leg extension exercise that causes injuries, it is the exercise equipment that causes the injury. I have found on some leg extension machines I feel strain/pain in my knees immediately.

I think that the trainers who know nothing, is that they know nothing about the biomechanics of the knee and the required engineering of machines to match the biomechanics of the knee. For the so-called experts to come out and admit this would mean that they are not so-called experts or leaders in the field but just followers. But most in the exercise field are just followers.

I recieved the RenEX DVD’s today, now going to start watching them

avatar db144 April 19, 2013 at 8:02 am

As usual RenEx can’t deal with the facts and attack those that disagree with you. First step is hide the truth and the second is to continue telling lies until people believe you.

The facts are RenEx, the child of SS, is a failed application for maximizing muscle growth. For 30 years the SS fools have blamed the equipment for the failure of the methodology and your “master” has grown fat “upgrading” the machines over and over again but now you’ve “fixed” the flaw with a new series of expensive machines or so you say.

Stick to the rehab business because nobody will reach their max. genetic muscular level using RenEx. If it could you’d be posting the proof instead of talking and talking and talking.

For all the BS you spewed about X-Force, Dr.Darden proved its effectiveness, repeatedly, and you still talk and offer no proof other than hearsay and speculation. Show proof or drop the continual
outrageous, empty claims you and your RenEx monkeys post all over the net.



avatar Joshua Trentine April 28, 2013 at 1:11 am

Dr.Darden is the benchmark huh?

I will bet I have prepared and trained more bodybuilders(natural) in the last few than all of his years combined.

I doubt there is a HIT facility in the world that has done more of this than we have. The funny thing is I’m not even pursuing people in that area.

@ Joshua,
I incorperated for a few workouts the shrugg on the OME as you suggested in a former article.I’m getting more out of it recently since concentrating on pro/retracting of the scapula at the end/start of the rom. Took some time to get the groove.
I agree with others that the dvd’s are worth the money .I ‘m using the TSC with succes with some clients and it accelerates their learning curve.And that is without a graphic device.

An “average lifter” is a person that does not have a physical ailment that requires special attention during training, not collecting disability or retired, not dangerously skinny looking for the next muscle in minutes fad to gain weight, not a competition attending bodybuilder or powerlifter, and finally not a convert who has built muscles and migrated to RenEx who now acts as if their body was built using only RenEx equipment (the marketing campaign is compliments of Arthur Jones).

Your everyday average lifter is one that desires to safely build muscle to enhance or maintain a level of fitness that will allow them an active lifestyle as they age. You know the group that constitutes the vast majority of the weight training world.

In reference to the attitude over using the word emaciated. The use of the word was accurate and it is your twisted minds that push your interpretation of the word into my statement. I don’t feel the need to sugar coat words to avoid hurting feelings. Seems you’d rather give someone a soft word and a pat on the back and not much else instead of telling them the truth and moving forward to find a solution. Please try to remember I’m not the narcissist that regularly posted videos and 10 year old photos of myself on Dr.Darden’s website all the while yelling look at me, look at me and what I’ve done.

As I said before RenEx is incapable of putting the facts forward but instead will talk and talk and talk. Oh, and try to run down anyone that doesn’t bow to the their supposed genius and newest gimmick.

You’ve had your shiny toys for more than a year. Release 12 or 15 case studies and results or keep talking, which is what you’ve done for what seems an eternity now.



avatar Joshua Trentine April 24, 2013 at 10:11 pm


So, you only want to hear from “average lifters” ?

By your own definition which excludes: A person with injury, rehab needs or pathology. Excluding extremely skinny people, excluding the retired or elderly, excluding bodybuilders and powerlifters and excluding anyone who worked-out with conventional methods prior to RenEx.

In the definition of “average lifter” we must also exclude those who do not have the mental capacity to differentiate between the ‘real & assumed objective of exercise’

@RenEx team,

I’m curious how you guys would go about a workout if you only had access to free weights or selectorized machines that are not properly cammed for the RenEx protocol. Josh, I know you have written quite a bit about using bodyweight exercises in the absence of good equipment. From what I have read, you guys still recommend 10/10 for bodyweight exercises? I’m curious if you guys limit range of motion on non ideal equipment, change cadence, etc. I seem to remember some of this being touched upon. This may be stuff covered on the FOE dvds? If memory serves me correctly Josh, on your squat video you were using 10/10 and a full range of motion?


avatar Joshua Trentine April 24, 2013 at 10:15 pm


This is the single most common question we get.

Ken Hutchins and I will be completing this DVD series for fall of 2013.


avatar Donnie Hunt April 25, 2013 at 5:54 pm

This should be really interesting stuff. I currently do most of my workout on selectorized machines. I feel like I am quite in tune with the various movements I do. When I reach a mechanical sticking point from fatigue I think about what Ken says about not caring if the weight will move, just keep contracting in good form. I will say that on the leg press I use, finding the right amount of resistance seems to be trickier than other movements.

Do you guys talk alot about “movement synergy patterns” in the ROE book and or the FOE dvds? Josh caught my attention touching on this fairly recent on bodybyscient dot net.

Cheers Josh,

however i have read that article, and it raised some questions, including the one i have asked here.

For me, i feel my option with standard equipment plus barbells/dumbells etc is to do a static hold for 60-90 secs to failure, prior to dynamic work as a way of mimicking Ren X TSC protocol.

Is this viable or have i missed the barn door ?

avatar Steven Turner April 22, 2013 at 7:58 pm

Hi Josh and Gus,

I have viewed the RenEX DVD’s and liked the DVD that Josh included on the bodybuilders who trained using RenEX protocol. It appeared from the bodybuilding DVD that many had reached their genetic muscular potential.

After watching the DVD on TSC I trialled the TSC on MedX equipment where I train by pinning the equipment in various position. I gradually increased the force until a point where I felt a an even level of force. What I found and at approximately 75 seconds I felt throughout the whole muscle a high level of muscle inroad – effort went up – muscle fatigued – I found that this was the same on all exercises.

The next time I go to the gym I an going to trial TSC/Dynamic method on a number of exercises and see what the results bring.

I highly recommend if anyone wants to make informed opinions/judgements on RenEx to purchase the DVD’s.


avatar Joshua Trentine April 24, 2013 at 10:12 pm


thank you for the feedback! glad you enjoyed!


avatar Jeffrey Muehl April 27, 2013 at 7:24 pm

I think Arthurs results were almost meaningless because static testing is inaccurate.

You can take all of the MedX research based on static testing and the conclusions from it for what it is worth and chuck it in the toilet. Basing a cam for exercise on the University of Florida strength norms was a joke. Static testing, even for research, is unethical. Arthur even knew it was dangerous and only recommended doing it just one time. Just read the patent on the medical lumbar machine….

All of that effort that was put into doing meaningless testing for meaningless non-scientific results. Too bad the funds were not spent improving the equipment instead. G and S barking up the wrong tree.



avatar Joshua Trentine April 28, 2013 at 5:43 pm

Lots of piling on RenEx out in internet world today….something I saw that I want to make clear:

“RenEx pricing is available by appointment only, nothing complex and nothing more”.

If anyone thinks that is unfair, then they can go elsewhere.



avatar Joshua Trentine April 28, 2013 at 5:44 pm

I know its popular to pile on RenEx , but I did not tell you that you need training to get prices. What I said was, the equipment is new and the features are new and a serious buyer would come into town so I could describe the features, the buyer could then tell me what they want, then I could quote them a price. Some machines can vary as much as $6,000.00 and you need to understand the “whys” and “what-for”.

I did tell you that your quote would then include a 1 day workshop….its called “a machine operators course”- it is where we come into your place or you come out to ours to learn basic operation, set-up and maintenance of your machine. We prefer a full blown RenEx certification if you are going to become a licensed facility, but what I state above is the minimum requirement. If you took the time to see the machines you would understand why.

I’m going to assume that I explained that poorly to you on the phone. If that is true perhaps you can post this on Dardens since I cannot.

Thank You

Hi Josh,

What is a high cost or a low cost?

I train at a gym where the owner purchased MedX equipment back in 1994 at a cost of approximately $6000 to $10,000 per machine (he told me the prices). that works out at about $500 per year. He has never had to fixed them and they have never broken down.

Go to most commercial fitness centre and they have a huge number of “cardio” machines prices ranging from $20,000 – $30,000 there are always a number of machines not working, to fix them can cost thousands of dollars. Some of the bigger commercial gyms can have up tp 50 diffrent types of cardio machines. Many of the weight machines are cheaply made and are often out of order and need replacing every few years.

Another gym I train at has Nautilus Nitro machines most PT trainers don’t train their clients on them but most don’t even know how to use the Nautilus equipment or the reasons for the cams.

If people are serious about RenEX they will make the appointment other than that most of your time would be wasted on people who are not genuine.

I am glad that db144 defined “average lifter” and that he doesn’t sugar coat things, he has now shattered my “ego”.

“If people are serious about RenEX they will make the appointment other than that most of your time would be wasted on people who are not genuine.”

The price on the equipment is crumbs when you can get up to $110.00/ session for 20minutes of your time….personally i know of no other way to make this kind of money.

Yes, db144’s definition was VERY helpful….really narrows things down.lol

The Criticism Of Men:

“Hodja and his son went on a journey once. Hodja preferred that his son ride the donkey and that he himself go on foot. On the way they met some people who said:

-Look at that healthy young boy! That is today’s youth for you. They have no respect for elders. He rides on the donkey and makes his poor father walk!

When they had passed by these people the boy felt very ashamed and insisted that he walk and his father ride the donkey. So Hodja mounted the donkey and the boy walked at his side. A little later they met some other people who said:

-Well, look at that! That poor little boy has to walk while his father rides the donkey.

After they had passed by these people, Hodja told his son:
-The best thing to do is for both of us to walk. Then no one can complain.

So they continued on their journey, both of them walking. A little ways down the road they met some others who said:
-Just take a look at those fools. Both of them are walking under this hot sun and neither of them are riding the donkey!

Hodja turned to his son and said:
-That just goes to show how hard it is to escape the opinions of men.”

I would like to see a Intellectual Debate between Brian Johnston and Joshua Trentine.

Brian has been discussing him for many months on other HIT forums and I am ready to hear the debate.

Sure we’re up to debate anything we stand for.

I’d like nothing more…what point have we made that is being contested?



avatar Joshua Trentine April 30, 2013 at 12:43 pm

For someone who spent a lot of time writing about the limitations of the “more traditional (HIT) exercise methods “, I’m surprised that he wants to use that as the benchmark for comparison. It’s funny that the first question is verbatim what he was being asked regarding all of his “methods”…

but I’m nobody, I’ve only written an article or two on machines…why would he want to debate me?

Hi db144,

I might not be the most intellectual person in the world but a life time of experience (forty years) in the fitness industry gives me intellect to think for myself. I have seen every “fad” in the fitness industry come and go and there are always so-called experts trying to “con” people. I don’t need anyone telling me about unethical practices in the fitness industry, I think I am in a position to make up my own mind.

db144 aren’t you up for the debate your the one coming onto this forum making all the criticisms and insulting people by calling them “average lifters”. And now you call in someone else to debate Josh, learn to stand up for yourself, standby your own criticisms and your own intellect.

Not much to discuss here. 30 years of muscle building failure doesn’t lend itself to discussion. Stick with the rehab operation and the juicy insurance payments.



avatar Joshua Trentine April 30, 2013 at 12:40 pm

Hi db144,

Overload Fitness does not accept insurance.



avatar John Parr April 30, 2013 at 12:44 pm

Starting to understand what Db is short for.


avatar Joshua Trentine April 30, 2013 at 12:49 pm

When recording performance we use “db” for dumbbell.


avatar John Parr April 30, 2013 at 12:56 pm

Yeah, that fits also!


avatar db144 April 30, 2013 at 1:32 pm

A rehab facility that doesn’t take insurance, give me a break.



avatar db144 April 30, 2013 at 1:43 pm

If the people here put some time into training instead of the 10 minutes a session once or twice a week on the new wonder toys they might see some results.



avatar Joshua Trentine April 30, 2013 at 3:05 pm

Hi db144,

I’m impressed to see that you are hitting the site 2x/day in light of us not posting anything new in weeks. Thank you for your continued interest.

I think you will really enjoy the stream of information on the new private site.

Have a nice day,


avatar db144 April 30, 2013 at 9:23 pm

Your pay site nullifies the naysayers while pocketing some coin in the process…nice.

How much will it be? I really hope its a reasonable amount so I can keep up here.



avatar Joshua Trentine May 1, 2013 at 4:29 pm

for you? $1000.00/ month


avatar Joshua Trentine April 29, 2013 at 5:35 pm
