I push carts at Wal-Mart for 33 hours per week on average.
I wanted to know what type of effect it has on your body muscle wise.
As far as cardio wise, I already know, since I lost allot of weight, but muscle wise, I'm not sure.
The carts are heavy, they are made of metal, and I push allot of them. With the amount of carts I bring in, it feels similar to the worn out feeling you get from lifting weights.
Also, the parking lot is uphill, so it feels like pushing carts up to a mountain top.
Whenever I bring in carts, I feel pressure on my legs, and my shoulders. My shoulders seem to have gotten bigger too.
