Why do we tend to think of good movement as the ability to ‘control’ our body? I think the term ‘body control’ is very misleading. It implies that you can control something that in reality you cannot. The only way to truly control something is to stop it or kill it. So trying to control your body will lead to less and less movement. Your body wants to be liberated, not controlled.
If I had to describe one key quality of someone who is skilled at movement, any movement, it would be the ability to fall without fear. Good movement looks effortles because it is, relatively speaking. It’s when you get in the way, or try to do too much, that you move poorly and make it more difficult. This 'doing too much' comes from fear and excess tension. You have to get out of the way. Let gravity work for you. Develop, naturally, the strength and resilience to support your movement, and learn to relax and let yourself move.
