I have bought a cheap pedometer at walmart, I have it all the time on me all day. Check it out. Also I walk for nearly 2hours at fast speed every other day. I think its very good exercise. Its very easy on your joints and doesnt wear you out. It depends on what you want in exercise, but I surely enjoy walking. Also when you have to walk for long time, try walking outside, it gives you enough distractions to keep you going.*
