I'm going to be more active in this thread (for a few days at least) since I've got severe writer's block on another project I should be working on....
High Intensity Interval Resistance Training
All of this comes from my search for a training protocol that allows for muscle gain/maintenance but also significant fat loss benefits.
Plenty of you are aware of HIIT cardio and its potential benefits for fat loss, but the problem is that its not great at building muscle and tends to eat too much into recovery, especially when dieting to get extremely lean such as during contest prep.
Then you have traditional resistance training sessions that are great at building/maintaining muscle mass but its impact on fat oxidation is extremely minimal - to the point where no intelligent bodybuilder lifts weights just to burn some fat...unless your one of those yoga type girls who loves random circuit training stuff to waste a few minutes (P90X with baby weights, etc).
So I was looking for some sort of balance between the fat loss benefits of HIIT cardio and the hypertrophy benefits of traditional resistance training.
And here it is...
Intro
I wont be going too into the science behind this approach (shocker!) but for those interested in the more minor details, it all stems from this free to read study:
High-Intensity Interval Resistance Training (HIRT) influences resting energy expenditure and respiratory ratio in non-dieting individuals
The authors did a comparison between a group using high intensity interval resistance training (HIIRT) and one using more traditional resistance training (8 exercises, 4 sets of 8-12 each).
To show just how impressive the effect of HIIRT on meta-bolic rate was, check this table out:
PubMed Central, Table 3: J Transl Med. 2012; 10: 237. Published online 2012 Nov 24. doi:* 10.1186/1479-5876-10-237
The traditional resistance training group saw an average ********* increase of 98cals over 22 hours.
The HIIRT group saw an average meta-bolic increase of 452cals over 22 hours DESPITE doing less overall work (volume).
This is better than HIIT cardio and with the added benefit of having the ingredients required (intensity, tension, damage & fatigue)to build muscle.
Very impressive.
I suspect that the main reasons for the impressive results were twofold:
1) The glucose meta-bolic pathways being directed to replenish glycogen stores first due to the excessive glycogen depletion that this sort of training causes. This allows lipids (fat) to become the preferred energy source.
2) Higher levels of AMPK & ANP leading to overall increase in fat oxidation.
And that's it for the science stuff, time to check out the routine:
HIIRT Programme
1x8RM
Rest 20-30 secs
1X2-3 reps
Rest 20-30secs
1x2-3 reps
Rest 20-30 secs
1x2-3 reps
Rest 2-3 minutes
That is 1 total set using the SAME weight throughout (your 8RM).
You will do:
- 3 total sets for legs
- 2 total sets for chest
- 2 total sets for back
An overall total of 7 rest-pause sets.
A few supplementary notes
- I strongly advice warming up before attempting a high intensity programme like this.
In the study they did 5 reps using 10RM but I personally prefer 2 x 2-3 explosive reps - both methods work.
- You need to pick leg, push and pull compound moves BUT avoid movements that increase the risk of injury due to poor form when training to failure, such as deadlifts.
- I personally prefer bench, rows and leg press but pick whatever your comfortable with.
- Do NOT be idiotic when it comes to tempo.
Controlled eccentrics with explosive concentric - this type of training is far too intense to be messing around with "focus on the muscle" slow tension type of stuff.
- Do NOT underestimate the volume in this programme.
The intensity is so high here that there is no need whatsoever to add a bunch of extra sets - in fact, you will get less quality results if you do.
- Do not do this routine more than 1-2x week and it should REPLACE one of your current sessions, not be added on top because this will be complete overkill when it comes to volume and you will suffer if dieting.
Summary
This programme combines a progressive tension overload (using heavy weights) with muscle damage and fatigue (low rest periods) - all the ingredients needed for muscle growth.
The study also shows that it produces extremely impressive increases in fat oxidation and meta-bolic rate - to the point where HIIT cardio looks like a relatively poor choice.
I have slightly modified the protocol from that seen in the study based on the results my clients saw, so it should be more effective than the original.
I will add that I've added a few touches here and there to make it even more effective but I'm saving that for another project.
