Pull-up exercise

It has a very good exercise effect on upper limb strength and back muscle groups. Hold the horizontal bar with both hands, slightly wider than your shoulders, let your arms hang naturally, and keep your body suspended in the air. Use the strength of your back and arms to pull your body up until your chin goes above the horizontal bar. Then slowly descend back to the starting position. If you lack strength, you can use pull-up equipment or do auxiliary training such as reverse rowing first. Pull-ups can strengthen the latissimus dorsi, biceps, trapezius and other muscles, and enhance the pulling strength of the upper limbs.
