Instead of dumbbells and barbells, only butterfly chest clamping, cross pull-down, parallel bars arm flexion and extension, supine arm flexion and extension pull-ups

Without dumbbells, barbell bench presses and the like, it is difficult to get a comprehensive exercise of the chest muscles, and the side, upper chest and lower chest of the chest muscles cannot be exercised. . . If conditions permit, it is recommended to use it, because the main instruments for chest training are dumbbells and barbells. . The equipment I'm talking about can only practice the middle seam and the side, which can barely calculate the expansion of the chest muscles, just like putting onions and garlic without meat, and it has no effect.

If you have abdominal muscles, you can just turn your stomach upside down. If you add some rotation and load, if you have a lower abdomen, you can basically meet the needs of exercise.
