Wide grip pull-down (mainly for latissimus dorsi) can shape a wide back, which is really suitable for many people. But for the whole back, it is a better idea to use diversified and balanced exercises. So try to use a narrow grip, and you will notice the difference between a wide grip and a narrow grip in the range of motion. In addition, this exercise has a good strengthening effect on the inner muscles of the upper back.
Preparation posture: sitting posture, feet on the ground, adjust the rubber roller to press the knee to keep the knee stable. Hold the lever inward with the palm of your hand, and the distance between your hands is shoulder width.
Exercise: Pull down the bar from the extended position to the chest, tighten the back muscles and keep the elbows close to the body. Bend slightly, hold your chest out, raise your chin, and keep your abdomen and lower back tense.
When the bar is pulled down to the top of the chest, the shoulder blades on both sides gather and clamp, squeezing the latissimus dorsi. Use the tension of the back muscles to control the lever to keep pulling down for about 2 seconds, then the lever will recover in a controlled way, and then stop for about 2 seconds when the arm is straightened at the highest point. Every time you exercise, you should feel the full extension of your arms and the stretching of latissimus dorsi.
