summary of the video with the time for reference:

1) PRONATOR TERES
PRODUCES PRONATION BY PULLING RADIUS
SLIGHT ROLE OF ELBOW FLEXION
STABILIZES RADIOULNAR JOINT AND HELPS TO MAINTAIN CONTACT
BETWEEN RADIUS AND CAPITULUM

2) PRONATOR QUADRATUS
MAINTAINS DYNAMIC STABILITY AT DISTAL RADIOULNAR JOINT
RESISTED/UNRESISTED SLOW/FAST PRONATION
THE DEEP HEAD IS ACTIVE DURING RESISTED SUPINATION

3) SUPINATOR
PRODUCES SUPINATION BY PULLING RADIUS
SLOW/FAST SUPINATION WHEN THE ELBOW IS EXTENDED

4) ELBOW FLEXED AND FOREARM PRONATED,
THE BICEPS GENERATES VERY HIGH SUPINATION TORQUE
BICEPS BRACHII

5) PRONATOR QUADRATUS
DEEP HEAD
MAINTAINS DYNAMIC STABILITY AT THE DISTAL RADIOULNAR JOINT DURING SUPINATION AND PRONATION

6) EXTENSOR CARPI ULNARIS
TENSION IN THE TENDON HELPS TO MAINTAIN ULNAR HEAD POSITION DURING SUPINATION/PRONATION

7)EXTENSOR CARPI RADIALIS BREVIS
STABILIZES FOREARM FOR GRIPPING DURING PRONATION TORQUE
PRODUCES WRIST EXTENSION FOR SUPINATION TORQUE
