Squat on the wall: stand facing the wall, with your feet shoulder-width apart, your toes touching the wall, then squat down and your nose touching the wall.

Squat down and stand up. Don't twist your body from side to side. Keep your body upright!

It's not difficult to practice for a while. You can put your feet together and the difficulty will increase immediately!

Push-up pile: similar to push-ups, the distance between fingertips is about 20 cm.

The fingers are opposite, the included angle between the hands is 90 degrees-120 degrees, and the elbow of the arm is bent about 90 degrees.

Keep this position as long as possible!

The so-called inner method is basically the result of psychological suggestion.

This need not be studied so deeply, sometimes simple things are more effective and closer to the truth!
