I usually sleep 9 hours a night. Usually after training and my pwo meal I feel like taking an hour or two nap. Will this help create an anabolic window?
Possibly, but it won’t make a difference.
If you sleep 10-11 hours day when will you have time for that thing called LIFE?
Naps are generally an okay thing to do, but if you already sleeping 9 solid hours a night its not going to be the difference between getting big or not. Focus on getting stronger in the gym, eating quality food, and if you feel like you need to take an hour nap after a workout, go ahead.
