 For example, punches will always be triggered by a circular hip movement, creating a shockwave transmitted to the arm; arm muscles will only help to control the movement, most of the power is transmitted by the hips.The same applies for kicks and projections.Some of the hallmarks of Hiroo’s Yoseikan Budo is the use of atemi (using feet, fists, elbows and knees), projections (essentially techniques from judo), sacrifice techniques (sutemi), self-defense including dangerous techniques (various joint locks, elbow hits), groundwork (ne waza) with hold-ons and joint locks, and work with weapons (bokken, wood stick, knife).
