Begin by lying down on the floor on your back with your legs perpendicular to the floor.
STEP 2
Slowly lower one leg to the point where you are no longer able to keep your lower back on the floor.
STEP 3
Lift your leg back up and repeat movement with your other leg.
STEP 4
Repeat movement on both sides for the desired or prescribed number of repetitions.
Special Notes
To increase the level of difficulty for this exercise, lower your legs closer to the floor. However, you should always keep your lower back on the floor. Once your lower back starts to arch too much, that means you have gone down far enough (or too far) with your leg(s).
