I've been enjoying the leg press machine lately. It's one of them where you put the pin in the weights and when you push it moves the seat back. Managed 10 x 180kg but that sounds quite a lot doesn't it? It doesn't say kg but everything else in the gym is kg. As I'm pushing the seat rather than the actual weights would body weight affect how much I'm actually lifting?
Generally the leg press is for bodybuilders who are too lazy to squat.
The pitfall of the machine is that people tend to be quad dominant, and the leg press accentuates this imbalance all the more.
