Absorb the Impact with Your Whole Body
Mechanism / Why It Happens
The higher you land from, the more reducing your landing speed helps soften the impact.
Imagine dropping an egg. If it hits hard concrete, it will crack because a large force is applied almost instantly. Now imagine dropping it onto a soft cushion instead. Since the force is spread out over a longer period of time, the egg is much less likely to break. Likewise, even when falling from the same height, increasing the amount of time it takes to land reduces the peak impact force during landing.

What to Do
Using your whole body to absorb the landing reduces the peak impact.
Landing with your knees locked is exactly like dropping an egg onto concrete. The impact is concentr
