SETUP: Grab a barbell (or an EZ-bar) and sit upright on a bench. Keep your chest up & shoulders pinned back to maintain great posture. Let the bar rest on your legs.
REP: Curl the weight up towards your shoulders by squeezing your biceps HARD, keeping those elbows tight to your sides the whole time. Lower the weight under control.
TIP: At the end of each rep, where our arms would usually go into full extension, they will be blocked by your legs. This limits the amount of forearm involvement in each rep, allowing you to really focus maximum tension on your biceps.
