The better you get the more it hurts. In the case of CrossFit, it hurts more because you’re doing the movements correctly. The bar – even if it’s weighted PVC initially – stays as close to your body as possible. You learn to keep your weight planted in your heels and to use a hook grip. You focus on the form that will produce the most energy not so that you can lift the bar but so that you can get underneath it before gravity has its way. You begin to focus on not only form and power but also speed and mobility.
