Instructions for TRX Alternating Leg Curl
Step 1: Lie on your back with your heels in the TRX foot cradles; legs are extended, and the TRX straps are set to about a foot above the ground.
Step 2: From here, proceed to pull your heels towards your buttocks.
Step 3: Press through your heel to lift the hips up. Essentially you are performing a bridge movement. Lift your hips to a maximum where your hips are in line with your knees and shoulders in a straight line. The shoulder blades remain in contact with the floor, and your arms are by your side pressing into the floor to help stabilize your torso. As you are lifting your hips, squeeze your glutes and pull in your abdominals to avoid overusing the lower back muscles.
Step 4: Proceed to lower your hips down as you extend your legs out, both in a controlled manner.
Step 5: repeat the movement several times.
