What is the best at home exercise equipment?

Answer 1

A mat, free weights, bench, push up handles, ankle weights, elastic bands. I don't recommend doorway bars or door hanging devices due to safety issues. Protective shoes, walking or running shoes, outerwear garments, appropriate socks, small pillow or according to beds and selected program. 

Answer 2

That depends on what level of exercise you want. For me, I mainly use my Wii and some of the exercise programs it has.
