Hi Laila,
I've seen your message and I experienced that situation too. I decided to take up dancing to keep myself fit. You should take it too!
Dancing is fun and you will more likely to stick to it. It also help us improved condition of our heart and lungs.
Other than that, it also make stronger bones and reduced risk of osteoporosis. Furthermore it give us greater self-confidence and also better social skills. I hope my decision will help you. Bye!
