Is boating really scientific?

Sitting rowing is a double joint exercise, which is mainly used to exercise our latissimus dorsi.

The standard posture is as follows:

1, the back waist is straight.

2, sink your shoulders and hold out your chest

3. Keep the neck neutral and don't move back and forth.

4. Try to keep the scapula still.

5. Stretch the shoulder joint naturally until it can no longer be stretched, then retract it in the arm, keep it for a while, and recover.
