The barbell (dumbbell) for resistance training of latissimus dorsi is pulled obliquely.

2. Training purpose: to improve the strength and endurance of the target muscle and increase the volume of the target muscle.

3. Instrument name: barbell and dumbbell.

4. Action name: barbell (dumbbell) leans over to paddle.

5. Design principle: In the process of bending over and paddling, the resistance is downward and the resistance is upward. In the process of resisting resistance, the body makes a shoulder extension action, because the target muscle has the function of extending the shoulder joint, so this action is consistent with the function of the target muscle, and this action can fully exercise the latissimus dorsi of the target muscle.

6. Posture: feet on the ground, legs naturally open shoulder width, knees slightly bent, knees crouched with hip joint as the axis, abdomen closed and chest held out, chin miniature, eyes looking straight ahead, ears, shoulders and buttocks in a straight line from the side, waist and back straight, body at an angle of 0-45 degrees with the ground, arms naturally drooping, hands holding a solid barbell (dumbbell), positive grip and middle grip.

7. Action trajectory: bottom-up, then top-down.

8. Range of motion: latissimus dorsi fully contracts when ascending, and the elbow joint is unlocked when descending to maintain muscle tension.

9. Safety tip: Keep your body stable, your back straight, your big arm as close as possible to your body, your barbell as close as possible to your legs, don't touch your legs, keep your elbows straight, and don't lock up.

10. Breathing and speed: exhale when ascending, 2 to 4 seconds; Inhale as you rise, 2 to 4 seconds.
