People take fitness seriously. Those ten thousand steps. Marathon over, time to tackle the ultra-marathon. Pounds upon pounds on the squat rack—just make sure to post it or it never happened. And yoga, well, people take their yoga very seriously.
Taking health seriously is wonderful, arguably better than not considering it at all. That said, one of the greatest joys of exercise is play. Your workout should be hard, otherwise you’ll plateau and never grow stronger.
