Exercise at home

The best exercise I do at home is walking. I also swim when the weather allows it. However, your question was about machines. I have several and they are very useful. The stationary bicycle is in my bedroom and it holds the clothes after I take them off and before I take them to the cleaners. My treadmill is in the garage....it holds up some rakes and hooes. I have a stepping machine, and it serves as a constant reminder to me to exercise as I always stubbing my toes on it!
