This drill is to make the body healthy and strong while working and hitting in all angles and to learn to relax in different tension points. Remember to tense and relax your chest and back and anything you feel you need to in all these positions to learn where you have tension so you can be aware of it and breathe it out.
Do this drill on the ground or on a wall depending on your state and available space. Imagine a line going from your naval to your head and place your fists on the ground so both thumbs face away from the line and relax for one minute breathing and relaxing the muscles. Change your position to thumbs pointing up and add another minute and after this slowly shake your hands letting the feeling of lightness or heaviness sink. Now add a minute with your thumbs facing each other and another one with them pointing downward.
