What are the skills of punching sandbags?

1, fighting consciousness: You must imagine a fierce enemy standing in front of you and pushing you step by step. You must go all out to prevent, fight back and hit hard! Hit him hard! Can't treat sth lightly, so-so, careless! Once the hand is empty, change the coping style immediately, always imagine the sandbag as a person, make a diversion, lead up and hit down, hit left and right, defend and counterattack, dodge, and hit the sandbag with imagination. You will feel the benefits brought by this practice in actual combat. 2. coordinate and relax. Relax, relax, and emphasize it every day. It makes you faster, harder and more energetic. It's like a storm. When you leave, relax immediately, adjust your breath, get nervous at the moment of hitting the ball and make an explosive force. When hitting the ball, tension is one tenth, and relaxation is nine tenths. Hold the group for three minutes, immediately relax the shoulder joints and arms, kick and hold a group, and do some massage.
