I hope my story is similar to yours. I've been biking a month and lost 15 lbs. I initially started out with a Trek 7.2 hybrid but when I worked up to 14 miles in a single ride my wrists hurt so bad. I couldn't drive for a couple of days because of the pain in my wrists. The bike shop was kind enough to let me trade it in for a road bike and I've been so much happier. The road bike was double the money but worth it. I can constantly change hand positions which really helps. I think the wrist pain was mostly due to me being so out of shape with such a weak core in combination with me being overweight. When the rainy season hits I'm joining a gym to do spin classes and work on my core strength. Next summer I want to be FIT.
