SETUP: Attach a straight-bar handle to a cable pulley and set it to a low height. Take an underhand-grip of the bar and pin your elbows tightly to your sides (like a T-Rex).
REP: Pull the bar up by squeezing the life outta your biceps, keeping your elbows close to your sides. Continue squeezing those f**kers even as you lower the bar.
TIP: This time we only want Partial Reps, and we’re working within the bottom half of the motion. So squeeze the bar hard and only go half way up. This will batter your forearms and biceps.
