• On Leg Curl Machine, contract hamstrings to bring heels to butt; hold
• Lower weight with control; repeat

Coaching points: Briefly hold contraction at top of movement // Keep movement slow and controlled // Go through full range of motion
Goodstein: The Leg Curls are a basic exercise for the hamstrings. Soccer players do lots of sprinting, [and] your hamstrings are a major muscle in decelerating your body when sprinting.
