BICEPS

21's

BeginnerBodyweight

This classic curl protocol splits each set into three parts: seven reps in the lower half, seven in the upper half, and seven through the full range, for twenty-one total. Breaking the movement into partials keeps the biceps under near-constant tension and produces a serious burn. It's a proven finisher for driving muscle growth.

How to do it

  1. 1

    Stand upright holding a loaded EZ-bar with an underhand grip.

  2. 2

    Curl the bar from your hips up to the point where your forearms are parallel to the floor, then lower it back down.

  3. 3

    Complete seven of these lower-half reps.

  4. 4

    Next, curl the bar from parallel up to your chest and back to parallel for seven upper-half reps.

  5. 5

    Finish with seven full curls, moving from your hips all the way up to your chest.

  6. 6

    Keep your elbows fixed at your sides throughout all twenty-one reps.
