It's Crunch Time! 2-Week Challenge to 100 Crunches
3 of 5
Lying on your back, lift your legs in the air with your knees bent. Place your hands on the floor beside you.
Without momentum, use your lower abs to slowly curl the hips off the floor and into your chest. Slowly lower them back to the starting position.
This counts as one rep.
