In the evening on Labor Day, Connor, Paige, and I went to a group tennis lesson with Coach Cristina. The kids have been going to her lately and it's a pretty good workout and she has great feedback. It was my first time going. The court is in her neighborhood, just south of ours, and Connor drove us over. It was a hot day and it was a pretty high intensity hour and a half workout without a lot of downtime. The kids both hit well and I was impressed with their consistency and with their serves. I took a time out during the serve workout to give my shoulder a break as it's been bothering me for a while now. It gave me a chance to take some pics and videos of the kids.
