What is the best and low cost exercise equipment out there?
So far every treadmill that my family owns keep breaking. Even the elliptical broke but I am not sure it broke because of our weight or if it is because my brother keeps tempering with it.
I think the equipment is overused. Does it have any exercise equipment that could handle the pressure of four people working out on it?
