To survive in the desert you need water. One of the many ways to make water is to dig a whole and line it with a dark plastic bag (like a big trash bag) and put many big stones there. When the temperature is low water condense on the surface of the stones which loose heat faster than the outer shell and accumulate on the bottom. Now take a plastic tube like the one used in camelback products or garden supplies and drink.
This is one from the children dvds by Mikhail. Have one person on his back rise to a bridge or a neck bridge and have the rest crawl under him or in pairs and revers. You can modify the hight and move around if you can to relax in this position and of course learn to use your eyes to see in a place of discomfort. Remember the goal of the drill makes it what it is and brings our body to do the work with effect. Work smart not hard.
Take something that is fragile like an old umbrella or a rolled up newspaper and lean it against the wall. Now test placing more tension on it and from various angles slowly and than do the same without looking at it. Work with a partner or against anything you can (a post, a chair) to push and guide with it without loosing it’s structure and gain a knowledge of how to work with improvised tools that were not built for this job.
Take a sturdy staff at least as high as your chest and take it in both hands (vary the width of the grip in your work) facing the same way. Now push and pull your hands with the intention of delivering the tension to the fists and keeping the torso, neck and shoulders relaxed as possible. Do the same with each hand in the opposite direction and than overhead and behind your back. Note how this makes you feel and keep breathing at all times. Doing this while sitting allows for more awareness to the upper body.
Take a partner or a heavy object and lie on the ground. Now have the partner relax and hold two of his limbs (only hands or feet or a combination) and start to roll and move with your body as you take your partner with you. Work so your arms remain relaxed as possible and use your position and body movement to propel your partner with you. This is a way to learn to work from the body. Now do the same drill as he tenses up a part of him or the whole and see how you can learn to recognize your own tension and use it to do the work. The head can also be taken or anything else but be careful not to harm anyone in learning and as little as possible during pro work.
Take your weapon in your hands (stick, gun and anything else that serves you so) and shadow fight people trying to take it away from you and don’t forget they will kick and hit and do more to get the job done so don’t focus on the weapon. Stay calm and do the work.
