I'm still a newb, but first I would like to say to all the people here who deem leg presses as useless... nevermind, you're not worth it.
Been training almost a year now, I was born with strong legs, they're much stronger comparatively than the rest of my body. I love to do squats, but my back can't handle much weight yet (6 reps atg with a measly 165lb) , so I always go to the leg press after my squats to put on some real weight.
I've always done leg presses with nice full reps, heels touching my ass, but once I reached 200kg (440lb), I felt too much strain in my lower back. So now, anything above 200kg I stick to a 90 degree angle or just a bit past fearing for my back. With this form I'm up to 320kg (700lb) for 8 reps and I'm sure I can do much more, but I've only changed the form since a month or so.
Question 1 - Is it right to switch form after 200kg? or will my back adjust after time to the full reps, if I just take it slow?
2 - Can somebody tell me a good way to warm up to 320kg? This is how I do it now:
warmup[ 80/15 120/6 160/4 200/2 240/2 260/2 280/2 300/2 ] working sets - 320/8 320/8 320/8 180/30-full reps
3 - What do you think of the working sets? The last one's a killer. Would I be better off saving time and just doing 2 or 3 of those?
I'm sure SOMEBODY here like leg presses like me, HELP!!
