10 Kettlebell thruster (explanation and standard here)
Some direction from the Mike Burgenger on the jerk grip verses the clean grip. You must transition between the two during a clean and jerk. During the thruster, you either transition (quickly!) or make some compromise in one or both. If your front squat is collapsing chest forward, keep those elbows up until the last minute. If the upper portion of the lift is the limiting factor, then drive up with your elbows down and your hands around the bar. Just make sure that your elbows do not come near your knees, for that contact at high speeds and with weight on the bar can lead to injury.
