Tucking will make you start rotating in the air - performing a flip - and letting go will once again return your momentum mostly to normal.

As you tuck you will actually accelerate to the ground faster, and as a result you can alter the distance you travel. Mastering this in addition to your starter squat will help you clear every stage.

When it comes to touching your feet on the ground, you will of course want to make sure you are flipping just enough to let go of your tuck and touch your feet on the floor at the end. One flip will do for most stages.
