squats, leg presses and upper body stuff.
At the moment I am in the gym 3 times a week doing squats, leg presses and upper body stuff.
Horizontal leg presses work the legs and the buttocks using a weight machine.
Why play with fire and risk months on the sidelines when you can get great workouts with much safer exercises like classic front squats, leg presses and leg extensions?
An alternative is to do leg presses in the gym, but try to get that acceleration element into the picture as well.
