I'm thinking of switching over to a 3 day per week full body workout for the next 8 weeks in order to change things up, perhaps burn some body fat and build a little more muscle. I've spent the past 18 months doing deadlifts, Squats, push day(bench/SOHP)and pull days (rows, pull ups) in the 5x5 mode and 5/3/1 modes. I've gotten very good results but now want to change things up and was looking to. see what others think. My plan is to incorporate many of the big lifts but stay in the 12-15 range (except deadlifts; my back doesn't like high reps) to keep the heart rate up. Any comments or advice is welcome.
