Grasshopper, too bad you don't live in South Carolina. We could learn together!

I would also recommend yoga, for 2 reasons. It will help alleviate the tightening of your legs due to the riding and make you more flexible, and it will increase your dynamic leg strength. Also consider weight training (moderate weight with higher reps) for your lower body.

I think that's a great idea. I'm going to sign up for Yoga classes to keep myself limber. I already do the weightlifting & I just think it's very important to stretch and stay limber.
