Have two or more partners walk through you and your job is to simply move out of the way and avoid being grabbed and taken either up/down sideways by them. After you do this walking drill for a while have one of them run through you and the rest keep walking. This way you have to relax and choose the speed you are working with each moment at a time. Play with the speed from super slow to sprinting and have a mix of it so you learn to see speed as what it is. Just another part of the work. This is a good drill to learn to relax the body and the eyes and of course to learn to avoid being grabbed. Keep your eyes from focusing and keep your shoulders and hips relaxed and moving all the time. Use your hands only if you must and make sure you don’t stop to move someone but move and move someone.
