4: the shoulder joints and the hip joints.
Hip and shoulder are both Ball and Socket Joints
The three main types of joints in the body are: ball-and-socket joints (hip and shoulder), hinge joints (knee and elbow), and pivot joints (neck).
In a handstand, several joints play a crucial role, including the shoulder joints, which provide stability and support, and the elbow joints, which help maintain arm alignment. The wrist joints are also engaged to support body weight and allow for balance. Additionally, the hip joints are involved, as they help to keep the legs extended and aligned. Overall, the coordination of these joints is essential for achieving and maintaining the handstand position.
Shoulder joints have the greatest mobility among the options listed. They have a wider range of motion compared to hip, elbow, knee, and wrist joints, allowing for movements in multiple directions such as flexion, extension, abduction, adduction, and rotation.
shrug
The back muscles, specifically the upper and lower trapezius, are involved in the shoulder shrug. http://www.exrx.net/WeightExercises/TrapeziusUpper/DBShrug.html
The movement where you shrug your shoulders is called a shoulder shrug. It involves raising your shoulders up toward your ears and then lowering them back down.
Using a shrug barbell for shoulder exercises can help improve shoulder strength and stability, target the trapezius muscles effectively, reduce strain on the wrists and elbows, and provide a more comfortable grip compared to traditional barbells.
You have ball and socket type of joints, in the both shoulder and hip joints.
Incorporating shoulder shrug barbell exercises into your workout routine can help strengthen and build the muscles in your shoulders and upper back. This exercise can improve your posture, increase shoulder stability, and enhance overall upper body strength.
