Pull-ups are a classic

Pull-ups are a classic exercise that tests the strength of the upper limbs and the back. You need to hold the bar with your hands either in a normal grip or an inverted grip, keep your arms straight and suspended in the air, and use your strength to pull your body up until your chin reaches the bar, then slowly lower it. It can efficiently strengthen the latissimus dorsi, biceps, and shoulder muscles, while improving core stability and upper limb explosive power. It can also be made easier with auxiliary equipment (such as elastic bands), making it suitable for people of different levels to exercise their back lines and enhance upper limb strength. It is an important movement for improving overall physical fitness.
