Before this lesson

Why this matters

Functional training can suit almost anyone — but benefits and priorities differ greatly between populations.

Evidence by population

  • Older adults: functional training improves muscle strength, physical function and activities of daily living [liu2014]. Tasks like sit-to-stand, stair climbing and carrying are directly trained.
  • General fitness (HIFT): high-intensity functional training combines varied multi-joint movements (lifting, gymnastics, monostructural cardio) performed at relatively high intensity [feito2018]. It improves aerobic fitness, strength and body composition in many studies, though study quality varies.
  • Athletes: sport-specific transfer (single-leg strength, rotational power, deceleration) supports performance [boyle2016].
  • Rehabilitation: progressive, task-specific loading bridges the gap from clinic to daily life — see early strengthening.

Common mistakes and misconceptions

Case study

A community centre runs one class with two tracks: older members perform chair sit-to-stands, step-ups and suitcase carries; younger members perform goblet squats, box step-ups and farmer carries. Both groups improve their 30-s chair stand or 1-km walk time over 10 weeks.

Key takeaways

  • In older adults, functional training improves strength, physical function and activities of daily living.
  • High-intensity functional training (HIFT) combines varied multi-joint movements at high intensity; it improves fitness but carries risk if poorly coached.
  • Benefits depend on matching tasks to goals and progressing load.
  • Enjoyment and social support in group formats help adherence.
