I'd 20 minutes to burn at the gym yesterday and had a go at the 45 degree leg press (for the first time in years)... no matter how much weight I put on, I was able pull off 5 deep reps everytime without too much effort. I worked my way up from 176lb and added 44lb for each set until I reached 440lb... it was still too easy. On the squat my all time 5RM is 264lb and the last reps made my head want to explode! I know the back muscles and abs play an important role, but I would never think it would make a ~200lb difference. Could something be wrong with my squats, or is part of the problem psychological, i.e. "oh fuck this huge weight I have on my back is gonna kill me!"? Or does everyones leg press max own their squat max? Thanks for any help!
