If you're working towards a 1rm goal, i would again suggest altering your reps. I'm starting a 6 week strength phase again on Monday that has me starting at 6 reps x 4 or 5 working sets, and each week as follows would be 4 reps, 2 reps, then 5, 3, and finally week 6 is your one rep week. I've had great results in the pas (worked my way up to 275lb 1rm @ 170lbs). I'm hoping to hit 300 at the end of this program.
