Leg Extension Machine
Before using the Leg Extension Machine, watch the video below, and read the instructions on the machine itself.
This machine targets the quadriceps. It is perhaps the most difficult machine to set up properly. First you need to align the knee with the axis of the machine. To do this, adjust the back of the seat so that when you are seated the back of your knees are pressing firmly against the edge of the seat. If you feel slightly reclined, this is OK.
Second, adjust the lower leg adjustment pad above your foot so it rests on your shins. This position will reduce unnecessary strain on your ankle.
Finally, make sure your toes are slightly in front of your knee. Most people find position #10 on the upper leg adjustment will properly place the toes where they need to be, and still give maximum range of motion.
