Well this is rather EXCITING! A study has found a way to almost DOUBLE your rate of Tricep growth. Yes, you read that right – double!

You can give this technique a blast during your next workout. Add it into your next THT Training session for the fun of it!




This study, published in the The Journal of Strength & Conditioning Research, took 44 guys with at least 1 year’s training experience under their belt and had them do Tricep Extensions or Skull Crushers (I like to use an EZ Bar when doing these, it’s just more comfortable on my wrists. I recommend you do, too).

The 44 men were split into 2 groups:

  • Group 1 used a PARTIAL Range of Motion (arms going from 45 degrees to 90 degrees only)
  • Group 2 used a FULL Range of Motion

And they trained like this:

  • 3 sets of 8 reps. (8th rep was reaching failure i.e. each set was an 8 rep max, like in THT we use a 8-12 rep max to failure)
  • 3 workouts per week
  • For a total of 8 weeks

Both groups made gains. But the PARTIAL RANGE group made MUCH better gains. Almost double.

They measured cross-sectional area of the triceps and the results were as follows:

  • The PARTIAL range group increased tricep size by about 49%
  • The FULL range group increased tricep size about 28%


NOTE: Before you read this rest of this, Scientific testing (EMG – electromyography) has revealed the 12 best exercises for every body part. You will maximize muscle activation levels by using these 12 exercises. I put the list with evidence for you below. Pop in your details below to get it (zero spam policy).


Give it a whirl during your next Arm Day on THT, or today (Wednesday) if you are doing the 3-day full-body THT plan (remember to download the Free MuscleHack App for Android and iPhone to track your workouts).

Is it any wonder The Arms Blast Experiment protocol produces such amazing results in 7-10 days? Arm Blaster guys know all about advanced Arm Techniques! My “Muscle Pulsing” method would be the closest thing to these partials – but it’s even better. And that’s just one of many unique methods employed to spark rapid gains in the triceps and biceps.


And the same goes for Advanced THT. Muscle Pulsing, Post-Activation Potentiation (a method I lay out for you here) and 7 other advanced techniques (for a total of 9) can produce the fastest, most impressive gains of your life. It’s like being a newbie all over again. You just have to put up with a little muscle soreness. But hey, who doesn’t LOVE sore muscles? 🙂


P.S. A “Shoulder Blast” is coming 😉 I think I have the techniques for rapid shoulder gains CRACKED (it only took me a few years lol!). And many of you guys have been pestering asking me to create this for the same amount of time! I’ll probably be recruiting “lab rats” to test it in January 2019. So look out for that, if you want to take part ~ Mark McManus 🙂


P.P.S. I know that putting together a diet for mass gains or getting shredded abs can be a pain in the butt, especially if you are new to this – that’s why I offer a service where I will do all the tough ground work for you.
You probably don’t know how many calories you need, or how many grams of protein, carbs or fat you need (based on your personal stats)…BUT I DO. Then I can take these numbers and create an exact meal plan for you to hit those numbers spot on! You’ll know what foods to eat and even when to eat them. All you have to do…is do it. No thinking involved. If you’d like me to take care of this for you, see the Get Me Shredded option on my Coaching Page here.
