Practice and cautions
No universal dose is assigned. Choose a manageable amount for your current capacity, leave room for controlled repetitions, and allow recovery. A clinician’s individual plan takes priority.
This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
