Glad you got back in the pool. It's tough getting back into exercise when you've been a way a while. But it's better you took the time off so you could enjoy your grandkids. I used to take a silver sneakers low impact class at the Y. I was the youngest but everyone, including the instructor, knew I had limitations so it was a nice class to take. I hope to join the MS aquatics class here at our town pool as soon as I have the time.
