When it comes to physiotherapy home exercise programs (HEPs), more isn’t always better. In fact, there’s growing evidence that giving patients too many exercises actually reduces the likelihood they’ll follow through with them.
Adherence to a prescribed physiotherapy exercise program is a key driver of successful recovery. Research consistently shows that many patients don’t complete their exercises as recommended — with estimates of non-adherence ranging from roughly half to two-thirds of all patients.
If exercises aren’t done, they can’t help. And that’s a major reason why many rehab plans don’t deliver the outcomes we expect.
Most clinicians and evidence summaries agree:
1–3 exercises: often the sweet spot — manageable and memorable. Patients are more likely to understand and follow these.
More than 3–4 exercises: compliance drops noticeably. Overwhelming numbers, especially with complex movements, tend to discourage patients.
High lists (6–10+): many patients will do none reliably — because the plan feels too big to start.
One clinical perspective summarises this balance: prescribing no more than 3–4 targeted exercises per plan improves the chance people will actually do them, whereas long lists overwhelm and demotivate.
Why does this happen?
Cognitive load: Too many exercises increases the mental burden — people struggle to remember what to do.
Daily life competition: Work, family, and routine tasks often crowd out lengthy exercise lists. Simpler plans fit more easily into real life.
Motivation drop: Completing a short plan feels achievable; a long one feels like a chore.
Here’s a practical framework:
1. Prioritise quality over quantity.
Pick the 2–3 most impactful exercises that directly address the injury or goal.
2. Educate on why each exercise matters.
When patients understand the purpose behind a movement, they’re more likely to do it.
3. Progress slowly.
Start with a simple base, then add exercises only as the original ones become habits.
Giving someone a long list of home exercises might feel thorough — but it often backfires. Evidence and clinical experience point toward short, focused exercise programs as the best way to boost adherence and get results.
