In fact, the push-ups we usually do can meet our physical needs. Open your hands and fingers to the ground, with the distance between your hands slightly wider than your shoulders, your arms perpendicular to the ground, your elbow slightly flexed, your toes touched the ground, your back was straight, your core tightened, and your elbow slowly flexed, so that your body fell close to the ground. After you go down, the angle between your elbow and your body is about 60 degrees. Inhale when you put it down and exhale when you lift it up.
