This post about how much Dwayne “The Rock” Johnson can lift is misunderstanding what he was attempting to achieve with this workout.

The rest of the Chest workout is fairly light-weight considering his size, so I assume he was trying to reduce his chest size for this role.

Got that exactly backwards. High reps at moderate weight == muscle hypertrophy and thus chest size increases.

Sure, Dwayne Johnson is strong. But he’s a Hollywood actor. It’s more important for him to look good than his absolute strength. This workout is designed for hypertrophy — it concentrates on making your muscles larger and not necessarily on strength (although you will get stronger, too, but not as much as a true strength workout).

I concentrate on strength so my workout looks a little different – I do weights closer to my max and fewer reps. This means I look less big but get stronger faster.

For The Rock, the workout makes perfect sense. Big muscles are his schtick (though he’s not a bad actor) and that’s how you get them. He’s working out exactly right for hypertrophy.
