I generally lift every 3-4 days, and run when I get the energy. My lifting routine says to lift every other day, but I've never felt good doing this, and like I said, I throw in running as well.
I took a week off of lifting. When I went back to the gym I had incredible energy. I lifted more than I have in a long time on lifts I normally do, and threw in a few new lifts for fun.
Could this heightened energy after a longer rest be an indication that I should be working out less frequently? Or, for maximum gains, should I stick to every 3 days anyway?
