It is perfect to practice with this sandbag, because when this is a professional training equipment, there is a professional instructor and a coach who knows how to punch, how to tie and how to tick. Swing your fist like this, and we won't get hurt. The rights movement is very, very fierce, and we may get hurt in the movement. So we should have a professional coach to guide us to practice boxing again. Before you can train, you should warm up and put your arms, joints, legs and wrists in place. Training should be gradual, not too violent at once, and attention should be paid to many things. Don't be too important. When playing combination boxing, rhythm is very important. Keeping pace with your all-round direction can make you faster, more stable and more accurate, so as to achieve the purpose of exercise. I hope everyone who exercises will listen to the coach's advice carefully, and it is our duty to study and develop this sport seriously. I hope our boxing match will flourish. It turns out that a new stage in Jincheng.
