Follow These Steps:
Step 1. While lying flat on your back (on the floor or a mat), extend your legs in front of you.
Step 2. Position your hands outstretched to both sides (for support) or place them under your buttock. This is your starting position.
Step 3. While contracting your abs (keeping your abs tight), slowly raise your legs off the floor. You should be exhaling as you raise your legs from the floor but maintaining a tight core. Hold the contraction for a second or two.
TIP: You can also bend your knees in towards your abs and extend them out in front of you again. Repeat.
Step 4. As you inhale, slowly lower your legs back to the starting position. Repeat these steps to complete your sets.
