isometric elbow flexion at 30 degrees with manual resistance from opposite hand, neutral grip position
Stand bending the elbow to 30 degrees with thumb pointing towards the ceiling and place the other hand on the forearm just above the wrist. Try further bending the elbow against the resistance of other hand. Hold before releasing the resistance and returning to starting position.
Nothing here is a prescription. Your physiotherapist decides which of these are yours, and when.
