text: how much weight can you lose with biking only? i'm thinking about an hour or two , 5 days/week. is it better than running? thanks with biking you dont burn that many calories. it would be better to go out and walk for the same amountof time and you could do nearley twice the work. i suggest since i'm a rower to try a rowing machine it burns calories like crazy. yet, for you i would suggest running over biking its a lot harder a better workout and you can lose weight faster. one more suggestion mix it up you dont have to do the same workout everyday. bike one day and run the next,
