If you don't want to try a personal trainer, train yourself. Start small: find a thing you want to improve. Plan out several ways you can practice that only take 30-60 seconds. Set a timer to go off multiple times a day. By practicing for a very short period of time, many times a day, it's easier to practice, and you build up slowly over time. You can also vary the intensity of these practice sessions, starting very light and building up.

If this sounds familiar, it's also called Grease the Groove by Pavel Tsatsouline.
