an hour of standing and moving around builds the body more than sitdown curls or dumbell benching
LOL - why dont you come to our warehouse, will give you an hours worth of filling orders of American Body Building cases, Muscletech cases, BSN and Gaspari powders, and then come and give us your brilliant deduction on how this type of exercise builds the body.
Umm.. nope. The most you lift and move around is around 50 pounds max, and only for a short time. While it does give you some strength, it is nothing like benching or curls.
