I just bought this french racing bike from the 70s or 80s for only 40 bucks. I've always lifted my upper body, but I'm thinking about getting my lower body in shape, along with my abs and lower back.

It's kind of fun when you go faster than cars, which doesn't happen often...but still.

I ride a little on my shitty ass mountain bike. I'd like a good street bike, but I don't have the money right now.

It is a good way to put some strength in your quads, but that and endurance are mostly all you'll get from riding a bicycle. It's also decent for the rest of your legs, but if you want to get stronger legs, abs, and a lower back, what you really need is squats and deadlifts.

I ride my mountain bike around to class and anywhere else I need to go.

I do plenty of lifting, I need to work on my endurance.

And unfortunately I can't squat, since my knee surgery it gets too swollen after I squat.

Yeah, pretty much this.

Oh I also wear a helmet. I imagine I look interesting with my hair all crazy.

get toe clip or clipless pedals. downfall is that your feet are sorta strapped down, but you can use your up pedal for mometum and work diff. muscle groups. speaking of which, does anyone know of the make clipless pedals but with a strap clip for your shoes so this way you can wear any shoe and not just ones with the clip in the sole??

I love it, I think I lost bunch of weight riding my bike to work and school everyday.
