I have been thinking about integrating all reps ranges in my training. Somebody here (graedy) proposed to alternate 3x3, 5x5 and 5x10 duting one workout, each with a different exercise, like this for example: Day 1: 3x3 heavy squat 5x5 medium press 5x10 light deadlift Day 3: 3x3 heavy press 5x5 medium dead 5x10 light squat Day 5: 3x3 heavy dead 5x5 medium squat 5x10 light press with 1 day rest between each this got me really interested, I've been doing the 5x5 starting strength for some months now, and although I'm seeing good progress and not quiting it right now, such a porgram seems to me to be quite good, because it incorporates different rep ranges. Does anybody have experience with this? My main question is: would it impair strength and power development for the sake of more muscular endurance, or quite the contrary boost it with more balance? I really have no experience. Also, I would like to incorporate something in the 15 and 20 reps range, in order to get conditionning and muscular endurance with the main lifts as well. So I was thinking doing something like this: Day 2: 5x15 squat 5x20 press Day 4: 5x15 dead 5x20 squat Day 6: 5x15 press 5x20 dead This *would* be well balanced, but I fear it is way too much. Also I was thinking about ncorporating Urban's complexes... Thoughts? Ideas? Any experience with such a routine?
