I did Epic Heat Day 48, aka 30 solid minutes of pushup variations, 2 days ago and boy I am feeling it too right through delts, pecs, lats, triceps, and abs. I cannot do a full clapping pushup but I was pleased to find out that I can do a full pushup and then lift up off both hands. Not bad.
@Cherryblossom81 I make an active effort to eat more protein than I used to but I don't count or calculate macros or anything. I will (for instance) generally have eggs for breakfast after weight training, eat more nuts and fish, etc. I'm getting stronger and seeing clear muscle definition so it seems to be working.
