First of all, stand up straight with your feet together, your knees together and your feet big. Then squat slowly with your knees together until you stop in a semi-squat position 10 second. Get down on the receiver, remember to straighten up, then take a deep breath and stand up. Change feet and merge, knees together, feet eight. Do it again.

The fastest way for boys to stovepipe

Stand with your feet slightly open and your palms pressed against the wall. Open your feet back and forth, bend your knees at the front and lean forward. Keep the heel and head in line. Don't leave the heel behind, be sure to stick to the ground.

4. Squat down and reduce thighs

Stand up and hold your head high. Feet shoulder width apart, feet parallel, toes straight forward. The soles of the feet can also be separated by a certain angle, about 60 degrees, but the direction of the knees should be the same as that of the toes when squatting. Squat slowly until the angle between your legs is less than 90 degrees, but don't be persistent and relax, just about 70-80 degrees. Then stand up straight in front of your thighs until you stand up straight.
