I am riding a lot right now to get ready for my OTTBs first show. I ride with correct, well sunk heels. So why is it that my calves are getting tighter is seems, with all the incredible stretching that happens while riding? (I ride hunt seat) When I wake up in the morning, my calves are SO tight, I have to stretch quite a bit. I didn't have to do this when I wasnt riding. I would think that the riding would have the opposite effect. Any thoughts?
