A stability ball is used to lift your hips and legs off the ground in order to do the hamstring curl with a ball exercise. By bending your knees, you will activate your hamstrings, which will allow you to roll the ball closer to your body.
In order to perform this particular style of hamstring curl:
Be in a supine position. The stability ball should be placed on your calves and heels. Flex your ankles and position your feet so that they are hip-width apart. Put your palms down and place your arms on the ground.
You should raise your hips until your body is in a straight position. Try to engage your glutes.
Raise your hips slow and steady while bending your knees. You should bring the ball closer to your body by pulling your heels toward your buttocks. Continue doing this until the soles of your feet make contact with the ball.
Knees should be extended, and your hips and back should be brought down to the floor.
Do between 12 and 15 repetitions.
Keeping one leg up or crossing your arms over your chest is an additional exercise that you can do.
