Shockwaves and Thai kicking

heres a few different shockwaves on the end of kicks

First the light snapping shockwave,Because the post will not give it forces him to snap straight back.

Now the deep snapping shockwave,and again the same principles as the punching but this time this tree has a bit of give and is possible to sink deeper into the target and more body weight,notice how he adds the step for more power

this is done by either stepping in rotating the front foot or jumping into position with one movement like Bukaw
