Good for you, Kathy, for getting back into the pool! You're inspiring!
I've practiced Yoga since I was 12, (I'm 51, now) and I'm totally in love with road biking. I try to get in 2 Yoga sessions a week, along with 2 bike rides. There are some weeks due to symptoms, etc., that I don't get in all I want. If today is a bad day, maybe tomorrow will be better.
I'm so grateful for all Yoga has taught me in stretching various muscle groups, etc.
