We can do a series of push-ups only by our own weight, such as push-ups with low hands and high feet, which is similar to the push-ups lying up in the gym. You can exercise well to the upper part of the chest muscles, and the angle between people and the ground is controlled at about 30 to 45 degrees. Push-ups with high hands and low feet can replace the parallel bars to train the muscles in the lower part of the chest muscles, but the effect is far less complete than the flexion and extension of the parallel bars. For the muscles in the middle seam and the middle part of the chest muscle, you can do push-ups on the flat plate, which is equivalent to the flat bench press in the gym. Narrow distance or wide distance can stimulate the muscles in the middle of different chests.
