Applying cardiorespiratory physiology to client programmes — FITT-VP, intensity methods, continuous and interval formats, progression and monitoring.
Learning objectives
- Write a cardiorespiratory prescription using FITT-VP
- Choose and justify intensity methods (HR, RPE, talk test, pace)
- Compare continuous, interval and HIIT formats
- Progress and monitor training safely
Before this lesson
Why this matters
Cardiorespiratory fitness is among the strongest predictors of long-term health. This lesson turns the physiology in aerobic fitness into practical client programming.
FITT-VP prescription
ACSM structures aerobic prescription around Frequency, Intensity, Time, Type, Volume, Progression [garber2011]. A typical evidence-based target for adults is 150–300 min/week moderate or 75–150 min/week vigorous activity [bull2020].
| Variable | Beginner example | Progressing client |
|---|---|---|
| Frequency | 3 days/week | 4–5 days/week |
| Intensity | RPE 11–13; talk test comfortable | Include intervals at RPE 15–17 |
| Time | 15–20 min | 30–60 min |
| Type | Walking, cycling | Mixed: running, rowing, intervals |
Intensity methods
Use at least two: heart rate (%HRmax or Karvonen — see heart rate zones), RPE, talk test, and pace/power. Combining physiological and perceptual measures catches errors from either.
Formats
- Continuous moderate — builds aerobic base, easy to tolerate.
- Intervals — alternating harder and easier work; useful for time-efficient fitness gains.
- HIIT — near-maximal efforts (e.g., 4 × 4 min at ~85–95% HRmax). Both HIIT and continuous training improve VO₂max, with larger average improvements for HIIT in a meta-analysis [milanovic2015].
Monitoring
Track resting HR trends, session RPE, HR at fixed workloads, and enjoyment. Re-test with the same assessment every 8–12 weeks.
Common mistakes and misconceptions
Case study
A 52-year-old client with knee osteoarthritis wants better fitness. The trainer prescribes cycling and pool walking, 3 × 20 min at RPE 12, progressing to 4 × 35 min by week 10 and adding 6 × 1-min bike intervals at RPE 15. Knee symptoms stay stable; Rockport-estimated VO₂max improves.

Short-answer & application questions
- Write a 12-week cardio plan for a sedentary adult with progression rules.
- Design a HIIT session for a client with knee pain who cannot run.
- List the signs that a client is not tolerating the current progression.
Key takeaways
- Prescribe with frequency, intensity, time, type, volume and progression.
- Intensity can be anchored to HR, RPE, talk test, pace or power; use more than one where possible.
- HIIT and continuous training both improve fitness; HIIT achieves similar or greater VO₂max gains in less time.
- Progress gradually — usually duration first, then intensity — and monitor responses.
