Kettlebell One Arm Jerk
The kettlebell jerk uses a short dip-and-drive from the legs to launch the bell overhead rather than pressing it up with the arm, which is what lets people move more weight overhead than a strict press ever allows. Timing the leg drive with the arm lockout is the actual skill here — get it wrong and the bell stalls halfway up. It's more about explosive coordination than raw shoulder strength.
