Lie flat on your back with your knees bent and feet flat on the ground. Extend your arms straight above your head. Engaging your abs, lift your upper body off the ground, curling forward towards your knees. Pause for a moment at the top, then slowly lower your upper body back down to the starting position. Repeat for the desired number of repetitions.
