Leg Curls

Primary Muscle Group: Chest

Instructions

Lie face down on a leg curl machine and hook your heels under the lever mechanism.  Your legs should be stretched out straight.  Now keeping flat on the bench, curl your legs up as far as possible, until the leg biceps are fully contracted.  Release and lower the weight slowly back to the starting position.  Hold on to the handles or the bench itself to keep yourself from lifting up off the bench.
