The back needs to have such a curve to be perfect

Whether the back is straight or not directly determines the beauty of a person's entire body. A back with graceful curves will not only make you look graceful and smooth, but also make you look much taller.

Step 1: Pull the strap to fly

Tie an elastic strap or hose to the door handle, hold one end of the strap in each hand, sit down and pull it tight so that your arms are at the same height as your shoulders. Then gently bend your elbows and slowly pull the strap back until your elbows are at the same height as your chest, tightening your shoulder blades. Hold for a moment, return to the starting position, and repeat 12 to 15 times.

Step 2: Single Arm Curl Exercise

Place your right hand and knee on a bench and grab a medium-weight dumbbell in your left hand with your palm facing up and your elbow slightly bent. Raise your left elbow to the same height as your shoulder, tighten your abdomen, and keep your neck and spine in a straight line. Lower it back to the starting position and repeat 10 to 15 times, switching to your right hand.

Step 3: Standing Flying Practice

Stand with your knees slightly bent, feet hip-width apart, and hold a light dumbbell in each hand with your palms facing each other. Lean your upper body forward parallel to the ground. Tighten your abs, keep your back straight, and slowly raise your arms to shoulder height.

Tighten your shoulder blades. Hold for a moment, return to the starting position, and repeat 10 to 15 times.
