I'm a carpenter too, most of the time. I take protein powder with glutamine in my empty cottage cheese containers and mix some water in and shake it. Beef jerky sometimes, nuts, and raisins for a late day boost. And a couple of sandwiches or some pasta or rice w/ veggies and meat for lunch.
Beef jerky fits in your pouch or pocket if they're picky about you stopping to eat. MRP drinks are a quick fix if you can afford them all the time. "Balance" brand bars are made with whey protein instead of the usual soy. And taste good.
I do because I can.
I can because I do.
Squat, bench, chin, deadlift, dip, row. The rest is secondary.
