The correct posture of doing push-ups should pay attention to the details such as keeping the body in a straight line, hands shoulder width, arms at 90 degrees to the body, legs together, and breathing coordination. This can better exercise muscle groups such as chest muscles, triceps brachii and respiratory muscles, and avoid waist injuries.

1. Keep your body in a straight line.

When doing push-ups, the body should be kept in a straight line and the core muscles should be tightened, which can reduce the pressure on the waist and avoid waist injuries.

2. Hands are shoulder width apart

When doing push-ups, your hands should be shoulder width, which can better support your body and reduce the pressure on your wrists and arms.

3. The arm is at 90 degrees to the body.

When doing push-ups, the arm is at 90 degrees to the body, which can better exercise the chest muscles and triceps brachii.

Step 4 put your legs together

When doing push-ups, the legs should be close together, which can reduce the pressure on the waist and avoid waist injury.

5. Breathing coordination

When doing push-ups, breathe in coordination with the movements, lean down when inhaling, and push up when exhaling. This can better exercise the respiratory muscles and core muscles.
