SETUP: Attach a resistance band thigh-height across two unmoveable surfaces. I’m using this squat rack because those two safety bars are locked in place (otherwise the band will pop off when you curl through it). Grab a weight plate and stand in front of the resistance band, chest up and shoulders pinned back for good posture.
REP: Squeeze the plate and begin curling it up through the resistance band. The tension will be highest in the top third of the rep (the opposite of regular dumbbells curls).
TIP: A good way to get to muscle failure from here is to step away from the band and continue to force out reps with the plate.
