You can analyse and use the olympics lifts in many many ways. One is to view the full skill is a pressure test for your front and overhead squat. The pure ” beautiful” form of the lifts are seen as the squat clean and squat snatch.
Put in other words, it tests if you own a superb front and back squat to the extend that you can jump into it with a great big weight. Any squat wobble or misunderstanding of your squat form means that, under pressure, you won’t be get under the bar.
Take home message: don’t skimp on your front squat and overhead squat practice!
