yeah, my hands start going numb too. I wish I knew a way to alleviate this. If that was not a problem I would not have many problems riding. I finally got the seat in the right position. Maybe someone here could help with that. I have a set of bar-ends that I use for different hand positions but this only does so good.
I am like addicted to this now.
I think that since I can't really lift weights I am pouring all of myself into this and it is taking effect on me. A good effect at that because burning up all of these calories is what I need right now. I can't wait til it gets even hotter outside either. Great time to finish a long bike ride and go jump into the pool.
