Pull-ups are divided into front grip, back grip, wide grip and narrow grip. The target muscles of exercise are different. You can exercise latissimus dorsi, teres major, lower trapezius, biceps brachii, radial arm and brachialis at the same time. Generally, pull-ups are more suitable for exercisers who need a little fitness foundation. This action is not recommended for friends who just started fitness. It is suggested that they can bend down to exercise their back muscles with barbells at first, and bend their arms and stretch their arms.

1: The horizontal bar grip is shoulder width, and the arms and upper body are naturally fully extended, fully stretching the muscles.

2. Pull vertically up to the mandible at a uniform speed, pause 1 s, and fully stretch the muscles.

3. Slowly descend to the initial position at a uniform speed to fully stretch the muscles.

4. concentrate on the whole process and fully feel the stretched muscles.

Keep the whole process at a constant speed, don't stop, don't rely on rebound and inertia.

In short, fitness is a sport that requires great perseverance. I don't want to do it many times, but I want to do every movement well, so that I can get twice the result with half the effort. I hope the above is helpful to you and I hope it will be adopted.
