Hypertension and Exercise: When to Hold a Session
A 61-year-old man in your phase 3 maintenance class arrives for his session. His resting BP measured twice after 5 minutes of seated rest is 176/104 mmHg. He feels well, denies headache or chest pain, and says he 'never misses a workout.' His medications are amlodipine and hydrochlorothiazide; he admits he ran out of his amlodipine four days ago and hasn't refilled it. His last recorded class BP two weeks ago was 138/84 mmHg. His prescribed session today is 35 minutes of moderate-intensity cycling at RPE 12-13. He is visibly frustrated when you ask him to sit down and recheck.
1. Decide whether to proceed with today's session and justify the decision against standard blood pressure thresholds.

Do not proceed with the prescribed moderate-intensity session today. His confirmed resting BP of 176/104 mmHg is in a range where initiating or continuing aerobic exercise is not appropriate until it is addressed. Standard guidance holds that exercise should be deferred when resting SBP ≥180 or DBP ≥110; his DBP of 104 is below that absolute cutoff, but the combination of an acutely elevated reading, a missed antihypertensive medication for 4 days, and a large jump from his baseline (138/84) makes proceeding unsafe and clinically unwise.
Reasoning to document:
- The acute change (≈38/20 mmHg above his own baseline) suggests loss of medication effect, not a stable treated state.
- Even if a single reading fell just under an absolute cutoff, the clinical judgment is to hold the structured session, encourage him to contact his prescriber about the refill, and recheck after he has resumed therapy.
- Light activity (e.g., slow walking) may be discussed, but do not run the prescribed 35-min moderate cycling bout.
2. He is frustrated. How do you handle the conversation and what do you offer him today so he leaves engaged rather than alienated?
Read the worked answer
Acknowledge the frustration first and separate the person from the decision: he is a reliable, motivated participant, and the hold is about a number today, not about his commitment.
Conversation structure:
- Explain plainly: 'Your pressure is much higher than your usual 138/84, and you've been off one of your medicines for four days. Exercising hard on top of that isn't safe today.'
- Give a concrete action: help him call the pharmacy/prescriber for the refill, and set a plan to recheck BP at his next visit or sooner.
- Offer a substitute that preserves the habit: seated rest, a short low-intensity walk only if his BP is rechecked and acceptable, a home BP log to bring back, and a review of his medication routine.
- Reinforce the win: emphasize that catching this is exactly why he checks in - it protects the routine he has built.
