‘Being active’ does not mean you have to be a 300 pound body builder, triathlon runner, or highly competitive bikini model. You don’t necessarily have to run, lift, play tennis, football, soccer, or do plyometrics.
'Being active’ simply means doing what you enjoy doing; what ever that may be. If you don’t enjoy strength training, then you don’t have to do it! If swimming is more your thing, then go for it! Do what feels right, and have fun with your physical fitness!
