Stance offset frontally to the soft mat placed on a bar. With both arms, alternate strikes from bottom to top (uppercuts) to the mat (underside of the opponent's chin). The elbows remain in front of the body and the opposite hand on the face for protection/defence. The legs and upper body are straightened simultaneously for the punch (use the power from the legs).
Uppercut:
The uppercut is the most difficult punch in terms of structure. It is triggered by hip rotation. In preparation, the fist and upper body are dropped slightly. The forearm is then brought up vertically in front of the body and the legs, hips and torso are stretched at the same time. The fist should hit the chin from below.
