Somebody that is watching the video with me commented taht it looks like you aren't setting your back properly before pulls. When you jerk, your back foot should be pointing forward
Stop the muscle cleaning or even power cleaning for that matter. When you are learning the lifts those will only hinder your ability to learn to do the real thing. I watched you muscle clean then do a muscle full clean. You need to practice and learn the full lift to the best of your ability before you should add any of the other things, if you still want to do them. If your goal is to learn to do the full lifts and do them well, think about heeding my advice, but if you just want to train to train then muscle cleans will be ok to do. Remember though, there are no world records for muscle cleans or power cleans.Ryan
Just wondering if that is a standard sized platform you are using. It looks a little short from front to back and I wonder if subconsciously you are not making a very deep split on the jerk for fear of your foot slipping off the surface? Maybe stand a little front of center after the clean before the jerk. Also having shoes will change the mechanics of the lift in general.
