Im 34 5’9" been lifting hard again for 6 months after having shoulder surgery. I have arthritus in my shoulder. Any ways I have three months coming up that i can get in the gym all i want, but i have to eat galley food, 3 meals a day. My question is whats good to add for meal replacement? I really want to take advantage of the gym time and put on some mass. I was plaining to bring tuna, almonds, protein shakes, any other ideas so i dont dive into the candy?
