I've been riding my commuter hybrid bike for the past week now about every single day. I usually ride about 20 miles or so a day. Non-stop, I do about 5 or 6 miles at a time.
I've been told by my friend/student health guru that you're not supposed to work out the same muscle everyday, because you need a day or two for recovery.
Does this mean that if I ride everyday, 20 miles a day, 5 days a week, that I'll lose muscle mass, strength, or anything like that because I don't take a recovery day? What would be the best way to counteract if that's the case? (I must ride everyday to commute. I hate the bus. :[ )
