1, stretch your neck
Tilt your head forward, but don't shake it from side to side-it's dangerous. On the contrary, stretch your neck to the left, right, front and back, but you must turn your head back to the middle first.
Tilt your head, put your ear to your shoulder, tilt your head back and keep it at a 30-degree angle, turn your head from left to right, and then turn left from right. Make sure that your head leans back slightly, your chin stays relaxed and your mouth is better open.
Step 2 stretch your shoulders
Put your arm on your chest. Hold the forearm with the other arm. Pull your arm until you feel your shoulders stretched. If you feel that your chest is being stretched instead of your shoulders, push the stretched arm in the opposite direction to contract your muscles.
Step 3 stretch triceps
Raise your right hand. Bend the right elbow so that the forearm is behind the head and hangs between the shoulder blades. The other hand touches and grabs the right elbow. Bring your elbow closer to your head.
