A Radically Effective Training Technique

Posted by Joel Marion on June 24, 2009

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)

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!

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

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?

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.

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.

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?

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.

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.

Yes, it is substantially slower than normal.

I normal just recommend that people lower under control and explode up on ever rep. Changing stimulus like this is always a nice change of pace to shock the body into new progress.

They’re great for strength and power development, so yes, are vary valuable for those attempting to lose fat.

You’d then use additional metabolic resistance training or HIIT as the “fat loss” workouts, but these workouts are great to maintain and even increase strength while losing fat.

For general work, the 2OX tempo is what I would recommend.

Periodically switching the tempo can be beneficial to induce new stress on the working muscles, but using the greatest load while still lifting under control is where it’s at for the bulk of your training.

It’s very easy to use either method when using machines or working out with a partner…it doesn’t require that you switch equipment or anything, so you’re just taking up one piece of equipment in the gym at a time.

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.

Great tip, you could pair push ups for the explosive portion and dumbbell bench press for the max effort portion…that would allow for a quick transition.

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

Max effort is just a heavier load – you are still trying to lift the weight as fast as possible, however, it will inevitably be slower because it is heavier.

The explosive contraction is done with a much lighter weight, which allows you to lift the weight with a much higher velocity.

No, you should always strive to lift the weight as fast as possible. Of course, it should be under control and with good form, but speed is everything.

You need a partner as mentioned. Weight change can be done within 5 seconds with a partner, even faster with machines (i.e. pull out the pin and reinsert)

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.
