You work 10 hours a day. That gives you 14 hours to lift, Prep meals and sleep.
If you sleep for 8 hours thats 18 hours of your day gone but Good news is you have 6 left. You have plenty of time to prep meals and go to the gym.
As arnold schwarznegger once said “you can have results or excuses not both”
Also there is plenty of big, strong people on here who have shift work ,yet still make it to the gym such as @MarkKO. Cut the excuses and get to work. Goodluck.
