I had a trial at a women gym once. It was fun and felt good. It is very hard though to get started and make yourself go. But I did it for a week. See if you can get a day or a week pass.
I also used to go a water exercise class. It really did help me. It was cool, cuz if you didn't want to become a member, they let you do drop in for $5 a time, just for the water exercise class.
I really did notice a difference. got more energy. that gym closed now though. Some days I would not want to get up and go, but I made myself, and then I would be happy. I didn't know anyone there, I went alone, I was nervous.
Now, I use the excuse that gyms are too far away, I don't want to drive 15 miles on the dumb under construction highway with tons of traffic, just to exercise. So, I've been walking around my yard and up and down the hill to my son's house next door, around his yard and back down. lol
