How much and how hard to exercise for metabolic health — dose–response, guideline volumes, HIIT versus moderate continuous training, resistance dose and breaking up sitting.
Learning objectives
- Apply guideline volumes for metabolic health
- Explain the dose–response relationship
- Compare HIIT and moderate continuous training
- Prescribe resistance training and sitting breaks
Before this lesson
Why this matters
The right dose balances benefit, safety and what the client will actually do.
Guideline volumes
- Aerobic: 150–300 min/week moderate, or 75–150 min/week vigorous, or a combination [bull2020].
- Muscle strengthening: 2+ days/week, major muscle groups.
- Reduce sitting and replace with light activity.
Dose–response
The greatest relative benefit occurs when moving from inactive to somewhat active. Benefits continue to increase with more activity, with diminishing returns.
Intensity
| Method | Notes |
|---|---|
| Moderate continuous | Easy to start; RPE 3–4/10 |
| Vigorous continuous | RPE 5–6/10 |
| HIIT | Similar or slightly greater VO2max gains in less time [milanovic2015]; requires screening and gradual build-up |
ACSM guidance individualises frequency, intensity, time and type [garber2011].
Sitting breaks
For people with type 2 diabetes, interrupting sitting every ~30 minutes with light activity is recommended [kanaley2022].
Common mistakes and misconceptions
Case study
An inactive client starts with 10-minute walks three times daily, builds to 200 min/week over 12 weeks, adds two strength sessions, and later introduces one interval session per week.

Short-answer & application questions
- Design a weekly plan meeting WHO guidelines for a beginner.
- Plan a HIIT progression for a cleared client.
- Explain dose–response with a simple graph.
Key takeaways
- WHO recommends 150–300 min/week moderate or 75–150 min/week vigorous activity, plus muscle strengthening on 2+ days.
- Benefits follow a dose–response curve — some is better than none, more is generally better.
- HIIT produces similar or slightly greater VO2max gains in less time, but needs screening and progression.
- Breaking up prolonged sitting helps glucose control.
