Hi everyone, I hope all is well. I've been training for 10+ years now, and recently my knees, elbows, shoulders, and wrists are prone to flare up after a heavy session. I love going heavy as most of us do. However, recently I've been considering switching my routine up and trying to focus more on an overall fitness oriented goal. I want to be able to be fully mobile and certainly don't want to get a knee replacement anytime soon. I have used support gear, but still manage to get something jacked up. Is it possible to maintain mass by drastically decreasing workout loads while increasing reps during a set and increasing the volume of sets? I was thinking about working in the 20 rep range. Thanks to anyone for input.
