How to perform the exercise:  To perform the seated leg curl, the athlete must set up the seated leg curl machine. First the athlete needs to adjust the seat so that the back is flat, and that the knee joint lines up with the edge of the seat. Next, the athlete must adjust the leg bar so that the legs are fully extended and the bar against the back of the lower leg, just above the ankle joint. Next, flex the knee, trying to achieve a 90 degree knee angle. Once this position is reached, the athlete may return back to the starting position. 

Spotting the exercise:  The spotter or coach can assist with the seated leg curl by pushing down on the leg bar if the athlete is unable to complete a full repetition of the lift on their own. 

Sport specific application: Hamstring development is very important in sports and is a muscle that is often injured. Sprinters, swimmers, or any athlete the requires large amounts leg strength to produce speed can benefit from the seated leg curl.
