A Deconditioned Client With Hypertension, Orthostatic Dizziness, and a 20-Week Deadline
Ruth, 58, a retired teacher, has not exercised in 12 years. She has hypertension controlled with lisinopril 10 mg and hydrochlorothiazide 12.5 mg; today's resting blood pressure is 138/86 mmHg and resting heart rate is 78 bpm. Her BMI is 31. Her physician cleared her for moderate-intensity exercise. She wants to "tone up and lose 10 kg" before her daughter's wedding in 20 weeks. She can train twice weekly for 45 minutes at home with adjustable dumbbells, a bench, resistance bands, and a treadmill. She reports knee stiffness going downstairs and occasional dizziness when standing quickly. She has never followed a structured program and is unsure how hard to push; she says, "I don't want to be sore for days."
1. Design the first four weeks using the OPT model, including acute variables and your rationale.

For a deconditioned beginner with hypertension and knee stiffness, I would start in Phase 1 stabilization endurance, not in a hypertrophy phase.
Acute variables:
- Frequency: two full-body sessions per week, 45 minutes including warm-up and cool-down.
- Sets: one to two sets per exercise in week 1, building to two sets by week 4.
- Repetitions: 12–15 for most exercises, stopping with several reps in reserve.
- Tempo: controlled, roughly 4 seconds down and 2 seconds up, with a brief pause where appropriate.
- Rest: 60–90 seconds between sets.
- Cardio: 10–20 minutes of treadmill walking at a conversational pace on two other days, or after lifting if time allows.
Exercise selection: box squat or sit-to-stand, step-up to a low box, dumbbell row, band pull-apart, incline push-up, hip bridge, and a standing calf raise. I would include ankle and hip mobility in the warm-up and avoid deep knee flexion early because of the stair stiffness.
Rationale: Phase 1 builds movement quality and connective-tissue tolerance while keeping soreness manageable. Her statement about not wanting to be sore is clinically relevant, not an excuse. Starting with one to two sets gives room to progress rather than recover from the first session for a week. Blood pressure should be checked before and after sessions, and she should stop if she feels dizzy or unusually short of breath.
2. How would you manage the dizziness on standing and monitor her blood pressure safely?
Read the worked answer
The dizziness is the main safety issue in this case. Hydrochlorothiazide can contribute to volume depletion and orthostatic symptoms, and her age and deconditioning add risk. I would not ignore it or treat it as a motivational problem.
Session precautions:
- Ask about dizziness at the start of every session, along with hydration and recent illness.
- Have her sit at the edge of the bench for 30–60 seconds before standing after floor work.
- Avoid rapid transitions from lying to standing and avoid breath-holding during lifts.
- Keep water available and avoid training in a hot room.
- Check blood pressure before training. If it is very high or she is symptomatic, do not train and refer.
Referral logic: If dizziness occurs repeatedly, worsens, or comes with palpitations, visual changes, or fainting, I would send her back to her physician. I cannot adjust her medications or diagnose orthostatic hypotension.
Monitoring: Record resting blood pressure and heart rate at each session, note symptoms, and use a 0–10 perceived exertion scale. A reasonable starting intensity is an RPE of 3–4 out of 10, not a fixed heart-rate target I invented. The reasoning is that safety and adherence come before load progression, and the physician remains responsible for medication decisions.
3. How would you progress her across 12 weeks, and what markers would justify moving from one phase to the next?
Read the worked answer
I would plan three blocks of roughly four weeks, but progression would be conditional rather than automatic.
Weeks 1–4: Phase 1 stabilization endurance. One to two sets, 12–15 reps, controlled tempo, 60–90 seconds rest. Goal: consistent attendance, no more than mild soreness, and stable blood pressure responses.
Weeks 5–8: Phase 2 strength endurance. If she can complete two sets with good form and no dizziness, move to two to three sets of 8–12 reps, tempo 3/2/1, and 60 seconds rest. Add a slightly longer treadmill walk.
Weeks 9–12: early Phase 3 hypertrophy or continued Phase 2. I would only move to three sets of 6–12 reps if movement quality is good, recovery is acceptable, and she wants more muscle-related work. Otherwise, more strength endurance is not a failure.
Markers that justify progression:
- Attendance of at least seven of eight planned sessions.
- No dizziness during or after sessions.
- Soreness resolving within 48 hours.
- Two sets of 15 reps with controlled tempo and no breath-holding.
- Stable or improving blood pressure readings.
- Better stair tolerance or a faster comfortable treadmill walk.
The reasoning is that phase progression should follow demonstrated tolerance. Her 20-week timeline is long enough that we do not need to rush the first month.
