The thing that always seems to be missing in these endless YouTube examples is footwork in conjunction with structure. I see one or the other or someone alternating between but almost never someone keeping good structure while moving. That’s fine for takedowns and grappling to break someone else’s structure. If you want to strike with any real juice then the posture, angles, structure and footwork to move that structure have to work in conjunction. It’s not surprising when people can’t make something work without moving their feet in coordination. I have said it many times, no foot, no punch. The same applies to a catch, grab, or standing lock. I am constantly reiterating the importance of structure as it relates to telegraphing. Watch yourselves in the mirror, pick up one foot, did your head move? Even a slight motion anywhere other than the leg lifting is a telegraph.
