Go to the usual push up position on the fists and tense and relax your body in parts and in waves. Remember to align the neck and head and to feel the body rather than remote control it with your eyes. Now go to half hight so the elbows are at 90 degrees. from this position slowly lift one arm relaxed from the ground and than when it is pointing upwards slowly raise your body up as well. This is a relaxation and awareness drill to learn to move from the body and letting the breath lead you under some tension. It is good to modify the idea to your type of personality and what is your focus at the moment.
