◾Jump, Land, Fall

You can add force to the right hand bone when the character jumps and lands. When the character is falling, make the hand bones move up and down.

Jumping does the same thing as Recoil, it applies a force to the character's hand, moves it, and then uses Spring Interpolation to make it return to its original position, so you can create a springy movement. This applies a force to the character's hand when the character jumps, lands, and falls.
