Always remember to stretch and warm up properly before climbing. There are a few ways to do so. You can start warming up your body by incorporating jumping jacks and some dynamic stretches into your regime. Ready your fingers by doing some easy exercises with a stress ball or by doing a bit of hangs. Once your fingers are warmed up, you can start by climbing a few easy routes before attempting your day's projects. Traversing (climbing laterally across) the boulder wall is also a good way to warm up.
No matter how old you are, just so long as you are mindful of your safety, climbing is a perfectly good sport for you. Any equipment that you need to start climbing can be rented from the climbing gym. In fact, you only need to bring one item to the climbing gym - socks - for the rental climbing shoes, and you're good to go.
