This is the usual pushing drill where you move with the direction you are pushed and add your own direction to keep you safe or do the job required. Start from standing up and have one or two push you in the body stomach, chest, upper back lower back and so on to twist and move and change your hight. Move minimally but keep with the people who are pushing so you are close and able to work your self. next lower yourself to a half squat and repeat the drill. This is exellent to learn to relax the muscles and to learn better balance as you work. The final stage is sitting and advancing while on the knees or at that level while being pushed. Keep from tensing against a push unless it is intended and controled. A knife will push through you and that is to be avoided.
