Start with a plastic bottle and press it to your body with just enough pressure to keep it on your person with your arms without using your hands. Have a partner work to take the bottle from you using pushing pulling and anything he or she wants and you simply move as you wish to keep the bottle touching your body somewhere. This is a great drill to learn to flatten knives on the body for children and older children and it teaches the value of movement and awareness in a fun and engaging way. Later on you will use a short stick and later on a knife to feel the more real objects at work and add more people and less awareness to the mix such as one closed eye or with a thick coat on to learn to move as you are.
Remember to keep breathing and remember it is not about perfect movement but simply getting the job done so you can go home to your wife and kids.
I got married on the third of this month and it is a great pleasure to have a person to share your life with. In Systema we learn to make the circle we draw around us larger and larger and it is also deeper in effect. Remember to keep your eyes forward and up and your heart clean.
