4. Reverse Crunch
The reverse crunch with a medicine ball may sound confusing, but the name makes more sense once you see how to do this activity. A crunch is a short situp, putting your abdominals to work by raising your torso off the ground while your legs remain bent. On the other hand, a reverse crunch is where you raise your legs while your torso remains flat on the floor. The medicine ball adds more difficulty to the exercise since there’s added weight on your legs to make you work against gravity.
Start by lying on the ground or a bench. Bend your knees to hold the medicine ball between them. Ensure that your grip on the medicine ball is tight so that you don’t risk dropping it on your chest. Lift your knees to your chest as far as you can go. You can also increase the difficulty by raising your lower back off the ground, intensifying the crunch. Hold the position for a few seconds, and then carefully lower your legs back to the starting position.
