The effect is very good, because the greater the weight, the greater the stimulation to the muscles. Push-ups with high pads are generally called downward oblique push-ups, which mainly stimulate the upper chest muscles, regardless of the stimulation to the upper chest of men and women, so even if the pads are up to the shoulders, it is no problem, step by step, and gradually advance.
In addition, wide-distance push-ups (1.5 times shoulder distance) stimulate the pectoralis major muscle more, while narrow-distance push-ups will increase the load.
