The shoulder joint is not harder to move, it just moves differently. It is a ball and socket joint, giving it a wider range of movement, but the elbow is a synovial joint, which can only move in one direction. The reason that yo may find it harder to move your shoulder is because the muscles pulling it may be less developed and also it has to pull up an entire arm, not just a forearm.
Primarily your Hip joint with its ball and socket, supplemented by the articulations of knee and ankle.
Moving our arms in a circular motion is possible due to the structure and range of motion of our shoulder joints. The knee joint, however, is a hinge joint designed primarily for flexion and extension, limiting its ability to move in a circular motion. The ligaments and tendons surrounding the knee joint also restrict its range of motion compared to the shoulder joint.
A pivot joint allows rotation around a single axis, like the rotation of the forearm. A ball and socket joint allows for movement in multiple directions, such as the shoulder joint which can move in all directions.
When you do a cartwheel, your shoulder, elbow, and wrist joints move to support your upper body as it twists and rotates. Your hip, knee, and ankle joints also move to help propel your body forward and provide stability as you transition through the movement.
The shoulder moves in three planes of motion: sagittal plane (forward and backward), frontal plane (side to side), and transverse plane (rotational movement). This allows for a wide range of movement and flexibility in the shoulder joint.
Joint Laxity
The shoulder joint is a ball-and-socket joint that allows for greater range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation. The elbow joint is a hinge joint that primarily allows for flexion and extension movements. This difference in joint structure contributes to the varying degrees of movement in the shoulder and elbow.
A lat pull down will move the shoulder and elbow the most, primary is probably shoulder.
this is because the partially movable joint wont move as easy r quickly as that of the elbow joint.
During the upward movement of a shoulder press, several joint actions occur primarily at the shoulder and elbow. The shoulder joint undergoes shoulder flexion as the arms move upward, while the scapulae also upwardly rotate to facilitate this motion. At the same time, the elbow joint extends as the forearms push upward, effectively straightening the arms. These coordinated movements engage multiple muscle groups, including the deltoids, triceps, and upper back muscles.
To move your arm without using the upper arm at the shoulder, you would need to rely on the muscles in your forearm and hand to create the movement. By using the muscles in your forearm, you can flex and extend your elbow, allowing you to move your lower arm without involving the upper arm at the shoulder joint.
The articulating bones in the shoulder are the humerus, scapula, and clavicle. These bones come together to form the shoulder joint, also known as the glenohumeral joint, which allows for a wide range of motion in the shoulder.
First flexion at the elbow, rotation at the shoulder and then abduction of the upper arm. The joint at the wrist doesn't change position.

The knee joint primarily allows flexion and extension, enabling the leg to bend and straighten. The hip joint facilitates a wider range of motion, including flexion, extension, abduction, adduction, and rotation. The shoulder joint, being a ball-and-socket joint, allows for extensive movement in multiple directions, including flexion, extension, abduction, adduction, and rotation. The elbow joint predominantly permits flexion and extension, allowing the forearm to move towards and away from the upper arm. The ankle joint enables dorsiflexion and plantarflexion, allowing the foot to move up and down.
When you push a door, the primary joint involved is the shoulder joint. The shoulder allows for the arm to move in various directions, providing the necessary force to push the door. Additionally, the elbow joint assists by stabilizing the arm during the pushing motion. Together, these joints facilitate the movement needed to exert force on the door.
