Crow / Frog to Handstand

Upper Back - The muscles in the upper back, including the trapezius and rhomboid muscles, help move and stabilize your shoulders. They pull the shoulder blades together and support posture.

Triceps - The triceps brachii muscle is located at the back of your upper arm. It extends your arm at the elbow and also helps move the arm backward.

Side Delts - The lateral part of the deltoid muscle, also known as the lateral shoulder, is located on the outside of the shoulder. It is the main muscle responsible for lifting the arm sideways. The lateral shoulder is particularly active when the arm is extended away from the body, such as during lateral raises or lifting objects to the side. It plays a key role in arm abduction and shoulder stabilization.

Front Delts - The front part of the deltoid muscle, also known as the anterior shoulder, is located at the front of the shoulder. It is primarily involved in the forward movement of the arm, such as lifting the arm forward. It also assists in the internal rotation of the arm. This muscle is engaged in activities that involve lifting objects in front of the body or pushing forward.

Forearm - The forearm muscles are divided into flexors and extensors. The flexors bend your wrist, while the extensors straighten it.
