Leg curls strengthen the hamstrings muscles.
In case you cannot see the video, here is a still sequence -
 |
The hamstrings curl with a Swiss ball helps to build up both the hamstrings and the lower back muscles. Lie on your back on a firm surface, with your hands by your side. Position your feet on the Swiss ball. |
 |
Straighten your lower back so that your body makes a straight line and your bottom lifts off the surface. |
 |
Bending the knees, roll the Swiss ball towards your buttocks. |
 |
Keeping the bottom up, roll the ball back to the starting position, and then back to the buttocks and home again. Repeat the exercise 10 times. |
