Leg Press Machine Mishap
We hate to break it to you, but you're using the leg press machine incorrectly. This machine is designed to target your hamstrings and quads, so it's unclear how you expect to achieve that in your current position, which doesn't appear very comfortable.
Proper usage involves sitting forward-facing. Perhaps someone should explain this to you before you risk injuring yourself. On second thought, maybe you should consider hiring a personal trainer to guide you through using the machines correctly.
