7:39, short head biceps articulates at coracoid process. Long head articulates at supraglenoid tubercle.

Forgot to mention, around 7:30, I go over biceps brachii originations. This is different from brachialis. Brachialis originates closer to distal portion of the anterior humerus and inserts near the coronoid process of the ulna. Brachialis muscle still flexes the forearm at the elbow but, doesn’t supinate like the biceps brachii Biceps brachii flexes the shoulder - due to its bi-articulate nature (influences 2 joints) Brachialis is uni-articulate and influences 1 joint (elbow joint). Performing mostly elbow flexion. Just wanted to clear this up.

6:30 , interesting , rowing , would you recommend to a patient as one fo the best for cardio / warm up ? thank you

How did you decide to get into Physical Therapy / strength coach ? it's very specific field. Please share the professional competitions , how did you place ? Thanks for the workout videos , and hello from Miami , FL 🌴

0:28, sarcomere is muscle cell

@2:53, I meant to divide front to back for coronal plane. Abduction at the glenohumeral joint is most easily observed from that plane.

I stumbled upon this and I really like your explanation. This got me thinking of my everyday movements and exercises. How do I reduce my risk of injury during compromising positions of an exercise? Like a pullup, for example, has both concentric and eccentric movement. Is starting from a state of isometry to eccentric., aka a gravity pullup, less at-risk for injury? Rather than a regular pull up, which has both concentric then eccentric movement. Some definitions I learned : isometric : no significant change in muscle lengths concentric: muscle shortening under tension eccentric: muscle lengthening under tension

This was a really great video! Can you post a video on different upper body warm ups to do pre upper body day?
