Recently, foreign sports medicine societies recommended a new way of exercise-arm running to the whole world. As the name implies, arm running is to replace running with moving arms. Medical research shows that arm running and running are similar in fitness effect. Because it is not limited by sports venues and there is no danger of injury, it is especially suitable for the elderly to exercise.

There are four basic movements in arm running:

1. Cyclist: Lie on your back, keep your arms straight, and do the same action as pedaling with both hands. 1 ~ 2 minutes.

2. Flying: Stand, spread your arms horizontally to both sides, slowly flap your arms and do the action of flapping your wings 1 ~ 2 minutes.

3, punching sandbags: imagine hanging a sandbag in front of you, punching sandbags, or boxing with an imaginary opponent, doing 1 ~ 2 minutes.

4. Throw the ball: Throw the ball into the air and catch it. Or throw the ball to the ground and bounce off the wall to catch it. If there is no ball, you can do simulation exercises. Do 10 times on each arm, and do 10 times after a short break.
