STEP 1. Lie on your back on the floor and raise your head and upper shoulders off the mat slightly. Lace your fingers from both hands together behind your inclined head for support while keeping your elbows wide apart. Do NOT bend your head toward your chest, keep it perpendicular to your torso but bend your knees 90 degrees, and raise your feet 1-2 inches off of the floor.
STEP 2. Then, lift your knees in a smooth arc toward your head while keeping everything else as still as possible. Once your knees are directly above your upper abdomen, pause, contract the abs, and then lower your feet back down slowly in reverse. Do not let them touch the floor though and ensure you continue to maintain tension in your abdominal muscles.
