Staying in shape is not the problem

I have never had a problem staying in shape. I have a natural gift, I think, and strength and endurance were never a problem for me. Besides that, I also just flat out enjoy staying active, and get antsy if I sit still for too long. This was a problem as a fidgety kid, but as an adult it really helps me keep my shape, even with my metabolism careening headlong into middle aged softness. I have a weight bench in my garage which I use once or twice a week, and I like to take long walks whenever possible. I have never before considered joining a gym, because I am a lone wolf and like to exercise by myself. Recently though I have been reconsidering this choice, and am becoming very intrigued by the idea of taking yoga classes. Yoga is a very different form of exercise then I have ever personally undertaken, and I am very curious to see if it will improve my flexibility. I am not a young man any more, and high impact exercise takes more of a physical toll on my body then it ever has before. I am hoping that with some regular yoga I can help to eliminate a lot of these nagging aches and pains that have been bothering me. I did some research and found three local gyms that all offer yoga classes, in all different skill levels. My plan now is to try out just one yoga class, see how I feel the next day, and take it from there.
