The 5K With a Red Flag
Dana, 38, is an accountant who has been sedentary for about eight years. She has already paid for a 5K in ten weeks and wants you to get her ready. Self-reported resting heart rate is 82 bpm, blood pressure was 138/88 mmHg at a drugstore kiosk last month, BMI is 30, and she takes no medications. Climbing two flights of stairs at work she notices 'a little tightness' in her chest that fades within a minute of sitting; it has happened twice in the past month. She had arthroscopic knee surgery three years ago and gets an occasional ache but no swelling. She says the chest thing is 'probably just being out of shape' and asks you to start her on intervals this week.
1. What do you do about the chest tightness before any program is written, and how do you say it?
Read the worked answer
Exertional chest tightness is a stop sign, not a training problem. Tightness on exertion that resolves with rest, in a sedentary adult with elevated blood pressure, needs medical evaluation before exercise. A coach does not diagnose it, does not call it deconditioning, and does not test it with an interval session.
- Say it plainly and without alarm: 'Tightness in your chest when you climb stairs is something a doctor needs to look at before I put you on a program. I'm not qualified to judge it and I don't want to guess.'
- Refer to her primary care physician. If it ever occurs at rest, lasts, or comes with shortness of breath, sweating, nausea, or pain into the arm or jaw, that is emergency care, not a callback.
- Do not clear her yourself because she is 'only 38' or because she already paid for the race.
- Protect the relationship: explain that noticing this is part of the job, hold her slot, and offer to work on non-exercise pieces (sleep, meal timing, stress) in the meantime if she wants.
- Document the reported symptom, the referral, and the date.
2. Assume she returns with written medical clearance and no restrictions. How do you assess her and structure the first three weeks, given the ten-week deadline?
Read the worked answer
- Re-confirm the health history and clearance, then assess current activity (steps, stair tolerance), knee history and current pain, and a simple walk/talk test to anchor intensity - not a maximal test.
- Set intensity by RPE 3–4/10 and the talk test ('full sentences, slightly breathless'), not by pace or heart-rate targets she will chase.
- Weeks 1–3: three sessions per week of walk-jog intervals (for example 1 minute jog / 2 minutes walk, repeated), full warm-up and cool-down, plus two short full-body strength sessions with knee-friendly movements (hinge, squat to a box, rows, carries) and daily easy walking.
- Agree knee rules in advance: pain no more than 2/10 during, no swelling the next morning, otherwise regress the interval.
- Renegotiate the goal. Ten weeks from sedentary to a 5K is aggressive; offer options - run-walk the 5K, or run a later race - and reframe success as completing with a plan rather than a time. She keeps the decision; you keep the plan safe.
3. What do you actually monitor week to week, and what do you avoid over-weighting?
Read the worked answer
- Session RPE and whether she could speak in full sentences - the simplest intensity check she can use alone.
- Completion of the three weekly sessions and total steps: process measures she controls.
- Knee pain during and after, plus next-morning swelling.
- Sleep hours and pre-session fatigue, since a poor night should change that day's plan.
- Symptoms: any return of chest tightness means stop and return to the physician.
- Body weight no more than weekly and never as the headline metric; early scale noise from new exercise can derail a client who is doing everything right.
