I only started riding last year again, and I feel like I've regained my wings. Please stick with it. As you tone the pain will fade, and you'll find what works best for you. Funny story, (well maybe not), on one of my first rides out I was passed by a car with a bunch of teenagers and one of the girls yelled out,"wheres the seat"? I immediately put the mothers curse on her of course, and almost gave up on riding. I didn't though, because that feeling of freedom was more important than the opinion of some kid who will now go on to have a kid just like herself (ha!) Pain comes in all forms, it's just a matter of getting over, around, or through it. Obviously, your on the right path. BTW, I'm 230 from a high of 260. There's lots of us out there.
