70 minutes on the Tred Mill? I usually do 70 minutes (speed walk for 10, run for 10) on the tred mill, but i started using a exercise bike and i like it better because i can sit down and my muscles don't feel as sore afterwards. Anyone know which machine would be more beneficial? I'm trying to lose 10lbs by the end of December. Thanks!
