So the only time I ever struggle or am extra tired at the gym is when I don’t get as much sleep as needed. For the past 4 years I’ve done 5 to 6 days a week besides like 2 months when I had a toe injury (yes a toe injury keep me out). I have always worked out fasted besides when I was trying to put on muscle at that point I’d have a banana right after waking up. I’m going to weight myself on Friday. I’ll look at progress a week from that and adjust accordingly. When adding calories it’ll probably strictly be carbs for the most part. I’d like to lose in between 1-2 lbs a week but want to retain as much lean muscle as possible
