Okay, so it’s been a month or maybe a year or, actually, maybe several years since you last saw the inside of a gym. That’s okay, no judgment here. But if you’ve now made the decision to start working out, how do you know what’s the right routine for your current age and needs? The twists and turns and weights and stretches you did in your earlier years may not be right for your current body- and may even pose some risk.

To start, take a look at this recent British Vogue article on how to exercise according to your age. Or, take a look at the advice from The Fine Line, which emphasizes that you need to listen to your body. You can start exercising at any age, but not every exercise is right for us as we get older. You may want to consider a personal fitness trainer to help you devise a specific routine for your needs or limitations. If so check out this list of questions to ask before you begin to work with the trainer. Or, you may want to consider the advice of former tennis star and now tennis commentator Chris Everet, who, at age 63, can probably still beat opponents half her age on the tennis court. Finally, if you’re hoping to get in shape without breaking the bank, grab your water bottle and read the National Institute of Aging’s Get Fit For Free recommendations.
