Some of my people tried it at home and it worked well.

But stick to it. It's no use if you don't insist.

Instrument muscle exercise

Here is to introduce a muscle exercise method without equipment to friends. When you don't have barbells, dumbbells and other equipment at hand, and you lack substitutes such as bricks and stones, but you still want to practice muscles, you can use static exercise.

The developed muscle method introduced earlier belongs to dynamic exercise, that is, during the exercise, the muscles contract and relax alternately, and the limbs move in space. Static exercise is characterized by tense and hard muscles, but the limbs are still. Static exercise can mobilize more muscle fibers, so it has a good effect on enhancing absolute strength.

Before static exercise, generally take a deep breath first, and exhale slowly during practice. The following is a static exercise method without instruments.

When you practice, you should hold your chest and abdomen, not bow your waist.

(2) Put your right hand on the right side of your head, press your head to the left, and apply appropriate resistance to your neck to prevent your hand from pressing your head to the left.
