Myths About Resistance Training, Checked Against the Guidance
Resistance Training: what people commonly get wrong, set against what published UK guidance says.
It is the only widely available intervention that meaningfully slows the loss of muscle mass and power with age, and it loads bone at the same time.
Key takeaways
- Guideline frequency: at least 2 days a week, major muscle groups
- Sensible beginner volume: 6-8 movements, 1-2 sets, 8-12 reps
- Most useful single change: Learn the movement with very light load before deciding what you can lift.
- Commonest mistake: Testing your maximum in the first months.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
These are the numbers the corrections below are measured against.
| Measure | Figure |
|---|---|
| Guideline frequency | at least 2 days a week, major muscle groups |
| Sensible beginner volume | 6-8 movements, 1-2 sets, 8-12 reps |
| Effort to leave in reserve, first month | 2-3 repetitions |
| Recovery between sessions for a muscle group | at least a day |
| Equipment required | none; bodyweight and bands both work |
Where people go wrong
What people tend to think, set against what is actually published.
- Testing your maximum in the first months
- Holding your breath during effort, particularly with high blood pressure
- Training through sharp or joint-line pain
What to do instead
- Learn the movement with very light load before deciding what you can lift
- Progress by slowing the lowering phase before adding repetitions
- Keep a written log, since progression is invisible without one
- Pick a regression you can complete with good form for every set
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Check with a GP before starting if you have a heart condition, uncontrolled high blood pressure, osteoporosis with a history of fracture, a joint replacement, or a recent unexplained fall. Seek urgent help for chest pain, severe breathlessness or fainting during exertion.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
