A friend has a membership to a gym with a swimming pool. I went with her yesterday. It's been a long time since I've been swimming. My muscles are sore. I used muscles I didn't even know I was using!
I love swimming, it is a good exercise. The advantage is you will not sweat in there. You need to warm up before going to swim again. Don't worry, your muscle sore is just temporary.
