Assess learners' ability to analyze and select appropriate exercise prescription adaptations for adults with comorbid type 2 diabetes, hypertension, and osteoarthritis. Scope: recognize contraindications and red flags; choose safe modes, intensities, frequency, and duration; apply joint‑protective modifications; plan blood pressure and glycemic monitoring and account for medication interactions (e.g., beta‑blockers, insulin/secretagogues); prioritize and reconcile conflicting goals across conditions; and justify progression and adherence strategies with evidence-based rationale.
