Hamstrings - Leg Press
The leg press in an exercise for the quadriceps where you sit into a chair and press a weight 45° away from your body. There are also vertical and horizontal leg press machines. However, most gyms have incline leg press machines (45°). The leg press is technically similar to the barbell squat. Its advantages are that the back is not stressed that much, you can't fall or lose balance, and you can stop any time or use your hands to push the weight back up. The biggest disadvantage is that the leg press doesn't boost testosterone production like the barbell squat. The free squat (with a barbell on your back) is the heaviest out of all free weight exercises and no other movement stimulates testosterone production in a comparable manner.
