Requirements for ballet floor rubbing: during the movement, the human body stands vertically and the body weight is evenly distributed on both feet. When the power foot sweeps the tail, the body center moves slightly to the main leg.

The strength legs are straight, keeping the shape of outward opening, and the soles of the feet are rubbed out close to the outside. The heel first leaves the ground, then the arch and sole of the foot leave the ground at one time, and finally the toes touch the ground. The distance that the toes are rubbed out is the farthest point that can be reached when the two spans remain stable, horizontal and motionless.

The route and process of the strength foot returning to the main leg are reversed in turn according to the action sequence of each part when it comes out, and the foot returns to the position before the action begins.

1, leg press: This is the most basic training content in basic skills training, including front, side and hind leg pressing. Leg press should pay attention to the upright leg joints, open and straighten the instep outward, and open the hip outward. It may be a little hard to press at first, but try to press each leg and control it for a while when you feel pain.

2. Kicking: Although leg press is in pain, he can't achieve any significant effect. The most important thing is to kick. When kicking, keep your body upright and your instep straight, and use the power of your instep to drive your kick. Don't worry if you can't play well at first. The point is that your movements should be standard, and you need to kick forward, side kick and back kick.
