Thanks! I was told that to grow you need 8-12 reps with 45 seconds rest periods. I was using lower reps, 5-8 and resting up to 3-4 minutes. I made good gains doing this but I think I have peaked out at all my major compound lifts, so I think the higher rep scheme might be a good change. But getting use to the 45 second break between sets has been a killer for me. You cannot do the same amount of weight when only resting a short period of time between sets.
