Take a number between one and ten and add one hundred to it. Now take as many steps as you  decided to and with every step both change your direction with your body and add a hand strike to it using the leg you stepped with. Note to keep your eyes with the direction of your body and to always keep your legs under your hips. Avoid falling onto the stepping leg by moving from the body first and letting the legs simply keep you off the ground. This is a good drill to prepare yourself for mass work and to always remember to work calm and with yourself in mind.
