While the kettlebell clean is usually considered a beginner exercise, I have found that a lot of people struggle to perform it. The skill set required to perform it successfully can be quite challenging, partly because the timing of the clean has to largely be based on the individual's sense of body awareness or "connectedness." If you pop your hips too fast, the kettlebell will shoot straight into you and you try to catch it. If you don't explode enough with your hips, your will end up curling the kettlebell up with your biceps. Furthermore, if you allow your elbow to move away from your body as you explode your hips, you will lose control of your kettlebell, and turn it into a modified swing. Check the video out, try out some of the tips, and see if they don't help you feel much more confident in your technique.
