This is an excellent Judo "foot skill" clip that include most of the leg movements that any MA will need (sweep, inner hook, outer hook, knife hook, front cut, scoop, block, ... but no inner twist and outer twist). What's your opinion about "integrate those skill into your system"? IMO, those kind of "foot skill" should have no conflict but enhance your IMA training. What's your opinion on this?
