Hello blades. Yesterday I was at the store and saw some "protein bars" with some vitamins and what not in them. I know protein is good for lifting weights and it said it gave you energy, so I bought a box. Would eating one bar before walking a few miles help me at all? I don't lift to many weights but I walk a lot. I also got some granola bars and some nature valley cardboard squares. Would a protein bar be a good or a bad thing before doing some walking/cardio? More harm then good?
