💪 The muscle you’re probably training WRONG

Hey -,

Most people – including myself – assumed that hammering a muscle in its deepest stretch automatically leads to more growth.

But the more I looked into it, the more I realized something felt… off.

So I did something most people would consider, well, kind of crazy.

I spent $40,000, brought in custom machines, and ran one of the most comprehensive studies ever done on the topic…

All so I could answer just ONE simple question:

Is stretch mediated hypertrophy really the key to building more muscle?

Now, there’s no question that getting some muscles into a deeper stretch leads to more growth.

In one study, researchers had people hold a max contraction with their legs fixed at different angles. 

When their leg was more bent — which challenges the quads in a more stretched position…

Their muscles grew up to 2x as much as when their leg was straighter and the quads not as stretched.¹

2x growth sounds pretty impressive, right?

Well, there’s just one problem…

Almost every study showing that training in the stretch helps muscle growth – what we’d now call stretch mediated hypertrophy…

Has only been done on the biceps, quads, or calves, because they’re easier and cheaper to test. 

But other muscles don’t stretch the same way, and some are built completely differently. 

Which means getting into a deep stretch may not be the best way to grow EVERY muscle.

So I worked with the experts to design a study that would test muscles that rarely ever get studied…

And see if the benefits of the stretch, which worked for the quads, calves, and biceps, would hold up when applied to muscles like the chest, glutes, side delts, and rear delts. 

I put my findings into a report (which you can read HERE).

In it, you’re going to learn:

• The ONLY 4 muscles where chasing the stretch is actually worth it (and the specific exercise variation for each one that research has confirmed delivers more growth)
• Why going deeper isn't always the answer (including the one condition under which full range of motion beats a stretch-biased resistance profile EVERY time)
• The calf training exception that breaks every rule (why HALF reps in one specific position outgrow full reps, and how to use it on your next leg day)
• The training variable that matters more than whether your exercise is hardest at the bottom or the top (and how most people are ignoring it while obsessing over resistance profiles)

Plus MUCH more.

PS: Almost every muscle responded the same in our MRI study. 

Almost. 

There's 1 muscle group where the stretch is SO powerful that half reps (yes, HALF reps) outgrow full reps…

And most people are training it exactly WRONG.
