Step by step

How to do the Ball Leg Curl

  1. 1

    Begin on the floor laying on your back with your feet on top of the ball.

  2. 2

    Position the ball so that when your legs are extended your ankles are on top of the ball. This will be your starting position.

  3. 3

    Raise your hips off of the ground, keeping your weight on the shoulder blades and your feet.

  4. 4

    Flex the knees, pulling the ball as close to you as you can, contracting the hamstrings.

  5. 5

    After a brief pause, return to the starting position.
