Which scenario is an absolute contraindication to starting or continuing an exercise program due to progressive worsening of exercise tolerance?

• A. Shortness of breath or exercise intolerance worsens even at rest.
• B. Chest pain occurs unpredictably or at rest.
• C. Mild fatigue after meals.
• D. High resting blood pressure.

Answer: (A)

Progressive worsening of exercise tolerance, especially when shortness of breath or exercise intolerance worsens even at rest, signals that the condition is unstable and that continuing or starting exercise could trigger a serious medical event. This is a definitive red flag that requires medical stabilization and clearance before any exercise program can be safely pursued. Chest pain at rest is also a grave warning and would prompt urgent evaluation, but the scenario described emphasizes deterioration at rest as the key indicator of unsafe progression. Mild fatigue after meals is common and not in itself a reason to halt exercise, and high resting blood pressure, while important to monitor, does not automatically block exercise in the absence of other symptoms or unstable signs. The critical takeaway is that symptoms worsening at rest reflect an unstable state, making immediate exercise unsafe.
