This exercise involves lying on the floor and propping yourself up on your elbows. You bend one knee and keep the other leg straight with the toe pointed up, then use your thigh muscles to raise the straight leg upwards for 5 seconds and repeat 10 times before switching legs. An easier option is to do quad sets if fully raising the leg is too difficult.
