Biomechanics of the swishmaster style jump push shot
The jump shot motion that the Swishmaster helps you condition is called the Swishmaster style jump push shot.
It includes three important motions. First, legs and trunk make a vertical upward jump (which is a steady acceleration base for the second thrust phase of the basketball.) Second, the arm pushes up quickly (as the main thrust to accelerate the basketball.) Finally, the ball is pushed by the wrist and fingers (as launch control of the basketball and the supplementary thrust of the basketball when needed.)
Comparison
Sling shot and Swishmaster style jump push shot
Sling shot is shooting the ball with arm and palm swing like a trebuchet (catapult). Sling shot which most players use is a relatively unstable jump shot method.

| Common miss-shot types and causes | 1 | Left or right deviation | Rare (due to elbow set deviation and weak triceps and deltoid) | Often (D 1,2,4,5,6) |
| 2 | Over or short | Major miss-shot cause(Wrong set point or rhythm) | Usually (over speeded triceps, hard follow through) | |
| 3 | Entrance angle too small | Never | Often | |
| Feedback from users | Strange feeling | Not easy to control every deviation factor | ||
