I change my rep scheme pretty often and I usually only go to failure every other week. I only work my muscle groups once a week, since I am on my first cycle and I feel myself recovering quicker, is it okay to go till failure every week, and more often per workout? I really want to force some good growth ans I am willing to go balls to the wall at the gym, but I just don't want to over train. What can you guys say from experience?
