Weight: Delivery Requirements and Final Submission

The kinetic sequence from bottom to top

The delivery phase is the culmination of all the previous effort. The sequence of muscle activation is critical: legs, hips, chest, arm, hand.

It begins with explosive extension and rotation of the right leg, which pushes the right hip forward.

The right heel should never touch the ground in this phase; it pivots on the metatarsal.

As the hip rotates and projects forward, the torso straightens and the chest opens toward the sector.

The throwing arm should not move independently until the chest is fully forward.

A classic mistake is to [bring the arm forward,] throwing only with the triceps and losing power from the legs and trunk

Blocking the left side

To transfer the velocity of the body to the ball, the blocking principle is used. The left arm and left leg act as a brake.

The left arm opens wide and then stops abruptly near the side of the body, while the left leg extends and digs into the ground.

This sudden braking of the left side of the body causes the right side (which carries the weight) to accelerate by inertia, acting like a revolving door or whip.

If the left side [goes] or turns too much (over-rotation), the energy is dissipated and the launch lacks final spark.

Departure angle and reverse

The final push of the arm should seek a release angle of approximately 40 degrees (slightly less than the theoretical 45 due to the exit height).

The athlete should feel the ball push [through] his fingers, ending with an outward flick of the wrist.

Immediately after the weight leaves the hand, the athlete should perform the [reverse] (reverse).
