I have been training heavy for months now, and getting kind of bored of it. I am only adding 1-2 reps on my last set every couple weeks or so, then moving up maybe 5 lbs on the exercises. Thinking about taking a bit of weight off for about 2 weeks and doing more reps. You guys think this will add a bit more strength or endurance going a few lbs lighter on all exercises and doing more reps for a couple weeks?
