…shoulders. So I'm new to bike commuting this year. I've only logged 100 miles this summer, but I think that's a pretty good start for an out-of-shape smoker of 18 years (recently quit, again.)

So I know I've got a ways to go before my body is accustomed to riding more, but last week, I rode to work (7mi round trip) and had ridiculous pain for two days afterward between my shoulder blades. Any ideas why? My hunch is that I slouched after a long day of work and let my spine sag forward between my shoulders? My bars aren't all that low, but am considering some taller riser bars for next season. Thoughts?
