I don't have that option, I can't take any kind of stimulant supplement, it'll fuck me up in a huge way. I can't work 12 hour days and then work out, I'll never sleep because if I lift after a certain hour I can't sleep.I get that way too. Although I still workout, I occasionally get the feeling that my workout just wasn't good enough. I started taking assault and that's helped me get in that zone tremendously.
I always workout at night as I work 12+ hours 6 days a week year round. So I usually come home from work, say hi to the wife and kid, change and down to my gym in the basement because I know if my ass hits the couch i'm probably not going to get off until bed time. LOL
Being 40+ with a goofed up metabolism is lots of fun. Enjoy your youth and health.
None of my business, but if you work 12+ hour days six days a week, THEN go workout, what type of relationship could you possibly have with your family?
