biking WILL burn MORE calories than RUNNING
you just have to pick the right stretch of road, over here in the UK its simple, a country lane or something
another thing is that biking will also work your quads, if you do hills it will build your calfs too
running is evil, the more you weigh, the more stress gets put on your kness, your a bodybuilder afterall, so putting on weight is a definate
biking can also aid recovery aswell, like after leg day, get rid of some of that lactic acid in your muscles, running will only make it worse
biking all the way, get yourself a pulse monitor and youve got the best method, in my opinion, of burning calories. just make sure you stay aerobic and not anaerobic.
anaerobic=muscle loss
I used to bike 5 days a week solid, I did sprinting, time trials, road races the lot, I was like a rake, but I never got any problems with my knees or shin splints, I had a restin heart rate of 38bpm (the average is 70) big legs and good calves and it was great going places, pretty fast.
I once tried running and I ran for an hour and half solid, I stoppped because I was bored and my legs hurt.
