(Ingrid Marcum finishing the Jerk)
The clean and Jerk is actually two lifts in one. The first part is the clean. It starts with the weight on the floor. You grab the bar with a shoulder width grip, and in one powerful motion, pull the bar to the shoulders, ending in a low front squat. You stand back up, as though performing a full front squat, then prepare for the second part, the Jerk.
At this point, you dip down slightly with the legs, and then blast back up with a huge thrust of the legs propelling the bar upward. You use your arms to finish the movement and end with them locked out.
