So I'm doing a 1RM sort-of workout for the next 5 weeks with bench/squats/deadlift. Squats and deadlifts have been fine since I work up from 50%x5 to 80%x1 but end with two sets of 5 at 65%. I take 2-4 minutes inbetween each set and it's no biggie, I feel fairly fresh until the last set. But bench press has been different. My 1RM is 250 and I've had a lot of trouble doing any more than 1 rep past 75% and this week the workout ended at 5 reps on 80%. I'm taking the same amount of time and it's the first thing I do before anything else (besides warming up/stretching). Obv. the risk of failing during a bench set is far worse than anything else safety-wise, but should I be concerned that I'm having a tough time pushing it at the end? Anyone with experience please chime in, I've mostly done circuits and 3x10s or 4x6s so this is new stuff for me.
