I have a friend who can max out the leg press machine (400 pounds). He is by no means a muscular or big guy and just started working out recently. I can do about as much weight, maybe a bit less, on all other exercises, but on the leg press I max out around 200 pounds. I have worked with a personal trainer in the past and he has shown me the correct way to work with this machine. I have watched my friend and he seems to be doing everything correctly, yet he can max out the machine. I don't have any problems with him doing this and I don't work out to compete with my gym partners, yet he continually rubs it in my face that he can do twice the amount of weight as I can and it just is starting to get annoying. Is there anyway that he is doing the machine wrong, or does he just have unnatural strength in his legs?
