Not everyone needs to workout. It's actually a failed USA, USDA program Healthy People 2010 that was reborn as the same name 2020 that had goals of reaching public health stats by those years that created his culture of fitness. The funny thing is it became an exercise in evolution or more aptly, eugenics. The rich. fit, smart people got fitter and the sad, fat, ugly people felt bad about themselves, starved to death, and bought useless crap to try and fit in.
Don't take my vocabulary as a personal insult but working out isn't all it's cracked up to be. It's something some people like to do. If you are serious about better health it's something you should do. But it is far from "cool" the way the USDA program has programed us to think it is. Frankly, those people are just in the way, playing with their phones sitting on things in the gym.
