Kick to the lower belly – Heel Kick (蹬脚)
Heel Kick (蹬脚) strikes into the lower part of the belly by the shoe heel.
It is effective in street fighting combats, but you should know it is very dangerous.
True kicks basically do not use the kicking leg’s muscles to lift the leg, but use the standing leg’s muscles and the core muscles in the hips and lower back.
