Really interesting protocol there. I’ll definitely have to look into giving this a try. Always cool to see new techniques and the impacts they have on the body. Thanks for sharing!
I’m just getting back from busting my butt in the gym with some Insider Contrast Training!
Insider wha?
Have no fear, I’m about to GIVE you all the details in today’s blog post.
The Technique: Insider Contrast Training
Where it came from: Insider Contrast Training was developed by French sport scientist Gilles Cometti and popularized in the western world by my good friend and Canadian strength Coach Christian Thibaudeau.
What it is: Insider Contrast Training is a unique method in which a particular training variable is manipulated during the course of a set.
Below are two of my favorite Insider Contrast Training protocols:
Variable Load/Concentric Contraction Speed Sets
With this method, the load and concentric contraction speed is varied every two reps. This works to increase strength, size, and power simultaneously.
(For those unfamiliar with the term concentric, it just simply refers to the “lifting”, not the “lowering”, portion of a given exercise)
Because weight changes need to be made as fast as possible, it is recommended that you have a partner and/or use machines that can be easily adjusted when utilizing this method.
If you do not train with a partner, it would behoove you to at least find someone at the gym to lend you a hand during your set-you’ll really be missing out by going solely with machines and neglecting movements like the bench press, squat, and deadlift.
An example set of 8 repetitions would look like:
Reps 1 and 2- max effort contraction @ 80% 1RM*
Reps 3 and 4- explosive contraction @ 50% 1RM
Reps 5 and 6- max effort contraction @ 80% 1RM
Reps 7 and 8- explosive contraction @ 50% 1RM
*1RM = 1 Rep Maximum, so if your max bench press is 200 lbs, 80% 1RM and 50% 1RM would be 160 lbs and 100 lbs, respectively.
Always strive to lift the weight as fast as possible. That said, explosive reps will be considerably faster then max effort reps because of the much lighter load.
Variable Tempo Sets
With variable tempo sets, the load remains constant throughout the set; however, the speed of both the eccentric (lowering) and concentric (lifting) contractions change every two reps. This is a great technique to stimulate maximum microtrauma (breakdown of muscle tissue) and subsequent muscle growth.
Here’s what it looks like:
Load- 75% 1RM
Reps 1 and 2- 604 tempo
Reps 3 and 4- 20X tempo
Reps 5 and 6- 604 tempo
Reps 7 and 8- 20X tempo
Tempo note: The first number is the time in seconds you should take to lower the weight (eccentric contraction), the second number represents the time you should pause between switching directions, and the third number is the time it should take to lift the weight (concentric contraction). A value of “X” means you should lift the weight as fast as possible.
So there you have it, not one, but TWO radically effective training techniques that you can begin using as early as today if you’d like. Talk about a fun way to shock your body into new gains in strength and lean muscle!
At least 100 comments and I’ll be back on Friday to give you a complete Insider Contrast workout regimen.
Talk to you in the comments section!

Hey Joel
nice post.
Do you think the focus is on the slow reps or the fast reps or is the combination of both that makes the most impact. The 604 rep is a slower than normal rep correct? or is that the timing people should always take (when doing a steady set)
June 24, 2009
If you train alone, the tempo method is probably the best to stick with and will definately create new stimulus as the sets will last 30 seconds+ of tension.
its always good to throw up some different tempos and give the muscles something ‘new’ to think about, will be trying a few sets this week for sure!
June 24, 2009
very interesting. can you give the scientific explanation why and how this will work?
June 24, 2009
Sounds great – something new to try. Its always important to shock those muscles
June 24, 2009
Sounds interesting. Can’t wait to hear more.
June 24, 2009
Hey Joel, interesting concept…would be nice to see how it translates to actual workouts…
Variable Tempo or just following some kind of tempo in my workout made huge difference in technique, strength and size. Is kind of scary the strength you can gain when you start using different tempos.
Hey Joel, Give us a workout I’m changing mine this week. Perfect timing
Thanks again for the great info
June 24, 2009
Are these techniques appropriate to those of us interested in leaning out? I am not looking to bulk up at all.
June 24, 2009
my man, C-Thib! always comin up with new programs.
June 24, 2009
posted earlier but didnt show up – need to inrease the post numbers people
June 24, 2009
Nice concept.
No doubt it would work.
Joel, In general do you think that the 604 set is a normal/average speed, or is this a slower set than most people would do.
Just curious if you think it is the faster reps or the slower reps that makes the gains, or if it doesn’t matter the speed – its just the fact that it is drastically different to the reps before it.
I know when ever I slow my reps down – say in a push up – I fatigue heaps quicker than if you were to bust them out. I have always found the slow harder, is it more efficient?
June 24, 2009
Bring it on
It sounds like it will also make working out more interesting–I like variety.
June 24, 2009
Joel,
Sounds like a great opportunity for max muscle growth.
My only concern is that it may get to complicated when put to use in the gym.Give us your thoughts on how to keep it all straight while doing it correctly.
Suggestions?
June 24, 2009
I used to do Systema classes (Russian Martial Arts) fairly regularly, and they seem to use that general principle a fair bit, not just in the strength training exercises, but in aerobic training (variable breathing rates, holding the breath for varying intervals, etc). It is tremendously effective for boosting general fitness, although as an asthmatic I found it to be a bit more than I could handle at times.
June 24, 2009
I don’t have a partner, I wonder if I could replicate something similar using bands. For instance, if I chose squats, I could hang the bands from the pull-up bar and do two reps without assistance, grab the bands for two reps, let go for two and grab them for another two.
I wouldn’t exactly get the 80% / 50% ratio but I bet I could get something similar. I’ll have to experiment.
June 24, 2009
That’s really interesting, though I’m having trouble totally visualizing the concept. Do you have any idea how I could research this more?
@Anna -
Hey Joel,
Great post!
I’ve used this method before with great success. In fact, all Christian’s work is well worth a look! But being a fellow Quebec-er, maybe I’m biased. :)
Cheers,
Adam
As it is always interesting to learn something new, I usually need a visual to really get more out of what your talking about. Is it possible for you to set up a video along with the blog.
June 24, 2009
Waiting for more info. Would you do more than 1 set? And how many exercises in circuit or superset? Would this be only for muscle growth or can it also help with fat loss?
June 24, 2009
Interesting. Am looking forward to more information on Friday!
June 24, 2009
Wow, interesting concept for variation within a set. Never thought of that. However, I have done variation between sets both in speed and weight. I appreciate always thinking outside the box to keep things interesting and growing! Thanks!
June 24, 2009
Sounds interesting, although there will be an inevitable delay between reps in the variable cotraction portion as you have to stop the exercise after 2 reps, change the weight and start again, stop, change the weight, lift, stop, and so on. For those of us that work out at home (without a parnet who can help change plates quickly), I am wondering about the effectiveness if the lifts don’t follow closely behind each other. I expect the benefits diminish with the longer delay between reps. Thoughts?
June 24, 2009
I think I’ll try the second option. I wouldn’t need a partner and I would be able to keep the weights the same.
June 24, 2009
Joel, love the method, we have had great success with this type of training….you have inspired me to put it to work in my own training session today…keep it coming!
June 24, 2009
forgot to add that if you do not have a partner, you can work the bench with a bar and do the contrasts with dumbells, just have them right by your side…even a push up with a vest works…it gets you in the ballpark and even shocks it up a bit more…variable appratus and loading…

I had the same type of question. 6-0-4 set seems really slow. I’m usually doing 4-0-2 sets. Is 6-0-4 the normal speed you recommend or did you slow it down for this technique?
Other than that, these techniques seem really interesting and I look forward to implimenting them. Thanks again Joel.

interesting variation
June 24, 2009
What to you mean by a max effort contraction and an explosive contraction?
June 24, 2009
I got to try this form my biceps. thx man
June 24, 2009
I’m a little confused by the “max effort contraction” terminology as well. Is there any reason why you wouldn’t be giving max effort for the “explosive contraction?”
June 24, 2009
Cool info, thanks Joel. I will try this.
The second method seems more workable to me. The first method seems like you’d end up doing a series of 2 rep mini-sets as you have to pause to adjust the load. Even with partners, I don’t see how they could do it fast enough to avoid that issue.
Sombody should invent a machine that could dynamically adjust the load…
I actually just tried altering my tempo through some sets of chest and back work recently and it really seemed to work my muscles hard, made the sets more challenging and I was able to work to fatigue. Interested in hearing more on this.
Interesting. Not sure how to incorporate the first into a set without too much stoppage for my liking. The variable tempo I certainly will give a try, however.
June 24, 2009
Used something close to the variable load version but with sets (for each load) of six or eight. Seemed to result in useful strength gains. I was trying to develop for both strength and power by doing this.
June 24, 2009
So, looking over this again I do have one consern about the explosive sets when doing squats. If you are exploding out of it, would this not increase the risk of loosing proper form and possibly hurting your back? Just a concern I had
June 24, 2009
good effort again- done similar before but not during a single set!
June 24, 2009
Are there any studies to demonstrate the effectiveness of these techniques?
Cheers

Alright, I am going to try this technique tomorrow morning with a few different types of routines and I will let you know how it goes. Thanks again Joel for your wonderful suggestions
June 24, 2009
Time to try it! :)
Great Stuff Joel!
I’m am going to give this a try. Nothing like something new to confuse the body into more muscle gain!
June 24, 2009
Does this kind of training work for someone who is not necessarily looking to build muscle exactly but to burn fat?
June 24, 2009
Looks solid to me – would love to see the complete program,
Thanks Joel!
June 24, 2009
sounds really interesting…but i have just one question;
If i had to increase and decrease the weights between reps..wouldnt that contradict the entire idea of “intensity”?? because it will take atleast 30 secs for me to change weights…so im actually resting between every 2 reps…and therefore it will not be that much intense…please explain further
June 24, 2009
looking forward to friday :D
June 24, 2009
could someone explain to me the variable tempo sets? i dont really get the whole numbering thing
thanks
I’ll give it at try.

Just hit the gym and gave this a try this afternoon!
Killer!

June 24, 2009
How long could you continue with this type of training? It seems like it is pretty intense?
not sure why my last post didn’t make it up but…
a way to do this with kettlebells is to do strict military presses then drop down into the bottom of a squat and perform Sotts presses (the more difficult of the 2). if you want me to make a video demonstration let me know on my blog ericjmoss.com
June 25, 2009
Tried this when it first came out from CT and didn’t like it (for me). Found the changing of tempo to be more of a hindrance than any benefit it brought. Now CT’s HTT training is a different kettle of fish, that does rock!
Hello Joel,
I am very grateful for the new technique that you have so generously made available for us. I did not find it necessary to have a helper around to change weights–maybe because I have a small gym station that allows me to change weights easily and quickly–anyway, from my perspective, you are a treasure-house of training information and thank you again for sharing with us!
I also have a question if I may ask it here: how long should a weight-training session be if I want to follow it up with an aerobic training (HIT stationary bike riding) after the weight workout. What my queestion boils down to is as follows: what causes cortisol rise in a trainee–weight training after 45 minute to an hour long training only or will cortisol also be raised if I continue after my weight training with my HIT stationary bike riding for another 50 minutes. I want to shed fat–I have a lot of it–40 ugly unnecessary pounds to lose.
Thank you for answering this question if you consider making time to.

So tried it with a couple of bicep workouts this morning. Did the variable tempo set doing hammer curls. Worked wonderful. really increased the intensity and gave some well needed variation to the workout. Loved it. Did the variable load one with preacher curls (since I don’t train with a partner I used the preacher curl machine). I didn’t like this type of training as much. I found it frustrating trying to quickly change the pin as fast as I could. It only took 5-10 secs do change the pin but it was distracting and slightly annoying. It would work better doing it with a partner. Also I found in the explosive reps it was so light that I felt like my hands and bar were going to fly into my face (maybe I went too light for the explosives). However, it did give a nice variation to the workout and it was a good change in the routine so I will probably use it on occasion. All-in-all really liked the techniques. Thanks a ton Joel. Love your posts and hope that we can get enought comments in order to get your workout routine for this. Thanks again.

sounds like a very fun and easy way to change up your routine workout.
June 25, 2009
Interesting ideas! I am always looking at ways to mix up my workout routine.
June 29, 2009
We need a few more comments to get that workout… And I want to see a whole workout put together so I can give this a try!










Hey, it’s Joel! So you want to know a little more about me, huh? Well, I’d be happy to oblige :-)
I guess it all started back in 2001 (my freshman year of college) when I was just a “skinny fat” 19-year old kid. At the time, I was spending close to 2 hours a day in the gym (now my workouts last about 30 minutes), and despite my efforts, you’d probably never guess I worked out a day in my life by looking at me...
