Getting Set (A)
With an ankle weight around each ankle, stand facing a wall with hands against the wall for support.
The Exercise (B)
Curl the weight up, flex your hamstring (the back of your leg) as hard as you can, and hold it for a count of one. Then slowly lower the weight all the way down to the starting position. After you have finished the planned number of reps with one leg, do the same for your opposite leg.
Tip
Don’t lean forward or stick our hips way out. On this exercise your whole body should be straight.
