sets

Focusing on sets and reps takes your attention away from what matters most when it comes to building size.
The more volume you do, the more you grow, but don't outgrow your capacity to recover.
Implementing drop sets into a properly periodized training plan will increase your chances of reaching your muscular potential.
It's time to understand the numbers. The key is to know what each is for and not to do more reps than you have to.
