Screening a Client with Controlled Hypertension
A 58-year-old man wants to begin a walking and light resistance program at a community fitness center. He has hypertension managed with a single medication, and his most recent reading at his physician's office 3 months ago was 138/86 mmHg. He has no chest pain, no shortness of breath at rest, and no diagnosed heart disease, diabetes, or kidney disease. He walks 20 minutes 3 times per week currently. He has never done resistance training. He asks whether he needs to see his doctor before starting, and whether he can use the center's stationary bike for hard intervals.
1. Determine whether medical clearance is required before he begins, and explain your reasoning using standard pre-participation screening logic.

The screening logic hinges on symptoms, known disease, and current activity level, not on a single risk factor alone.
Applying that logic:
- He has no symptoms (no chest pain, no exertional shortness of breath).
- He has no known cardiovascular, metabolic, or renal disease beyond controlled hypertension.
- He is already physically active with regular walking, which matters because habitually active people with controlled risk factors can generally begin light-to-moderate activity without prior clearance.
The reading of 138/86 is above the ideal range but below the stage 2 threshold that would typically prompt a medical referral before moderate exercise. A defensible conclusion is that he can begin light-to-moderate walking and light resistance training without formal clearance, provided he is told to stop and seek care if he develops chest pain, unusual breathlessness, dizziness, or palpitations.
Documentation matters: record the reading, the absence of symptoms, and the advice given. If his blood pressure were higher or he had symptoms, the answer would change to referral.
2. Decide whether vigorous stationary-bike intervals are appropriate now, and describe how you would progress him.

Vigorous intervals are not appropriate at the start. He has never done structured conditioning, and high-intensity work raises systolic pressure sharply during effort. The safer path is to build a base first and add intensity gradually.
Progression:
- Weeks 1-4: Walking 30 minutes on 4-5 days at moderate intensity (able to talk but not sing), plus 2 days of light resistance training covering major muscle groups with 1-2 sets of 10-15 reps at a comfortable effort.
- Weeks 5-8: Extend walking duration and add short faster bouts of 1-2 minutes within a walk, keeping the overall session moderate.
- Weeks 9-12: Introduce stationary-bike intervals at a moderate-hard effort, such as 1 minute harder followed by 2 minutes easy, for 4-6 rounds, only if he is symptom-free and tolerating the base work.
Throughout, monitor for dizziness, chest discomfort, or disproportionate breathlessness and stop if they occur. Encourage him to have blood pressure rechecked and to report the new program to his physician, and avoid breath-holding during resistance work to limit blood-pressure spikes.
