Word, keeping gains is super important. I also think a lot of injuries happen when people start a cycle when they haven't been lifting hard (or at all) and then go full steam ahead. I gotta keep lifting to keep the joints and tendons strong as well.
Same here 5 a week on or off. I workout 3 days take one off then workout 2 more and take another day off. But my body is split into 4 days. Chest/Bi's, Legs. Delts/Tris, Back/traps. With 4 routines rotating on top of 5 gym days, I get to hit differect muscle groups after the day rest when I am stronges & I dont burn out!
