I think I found my sport!

Boner, I agree a spinning class is more enjoyable than the treadmill.  My gym's classes are 30 minutes and we do various resistences and also standing and hovering over the seat positions.

Hi Guys, sorry for the blank profile, but I've been a long-time lurker on this sight and just joined today because I need to ask a question:  What kind of bikes and tires are you guys using?  The last time I tried to ride a bike I couldn't get the tires to hold enough air pressure to keep from going flat under my weight.  Is there a particular brand of bike or tire that can support a 350# frame?  Thanks!
