I really enjoy hang cleans. I love them because I find they work your whole body instead of just using a certain group of muscles. I would love to master them in the future because I feel like it is a very useful exercise to do, and it is very beneficial if you do them properly. My one success when doing hang cleans is catching the bar in a full squat. My one area to work on would be to keep my back at a good angle and not to slouch over.
Like I said, hang cleans using a lot of muscle groups. Hang cleans help my training because unlike other exercises, they help my full body get stronger. A place outside of class where they would help me is at hockey. The lower body part of the exercise really helps my skating.
