Ok, so I finally thought of something legitimate to ask about...so I bike ride at least 4 times a week. I listen to my I-Pod while I ride to make it more fun, but when I get tired of my music, I'm less inclined to go, besides, I'd like to do something else besides ride my bike all the time you know? I like swimming, but I don't have access to a pool all that regularly. I'm not that big on running, but I do power walk. I can't afford to go to a gym. Suggestions on exercise methods, please and thank you!
