I also love yoga, I have done it on and off for over about 20 years but now I do it every week, in fact, if I don't do it I feel like am seizing up. It helps keep me nimble and it will surprise you at how it helps you keep fit. It is not about doing weird moves, it's about strength, not only in the body but also in the mind.
Any sort of exercise is good for you but I have found that in my more "mature" years it helps me feel strong and definitely keeps that aches and pains away.
Even going for a walk is great for the mind and body. When people say they need to clear the head and go outside or for a walk it is a form of meditation as well. It can help slow down the mind and gain some clarity to go on with your day.
