Do not pause at the top of the movement. Keep movements slow and steady.
Instructions
Set up for the lying floor leg raise by putting a mat on the floor and laying down on your back with your legs extended straight out and your arms by your side with palms on the floor.
Get ready to start the set by lifting your heels off the floor slightly.
Keeping your right leg straight out in front of you off the floor, raise your left leg slowly up to 90 degrees.
Slowly lower your left leg back to the starting position without touching the floor and repeat the movement with your right leg.
