Weekend warriors: Cramming exercise into weekends works new UK guidance confirms
Key Points
- The 150 weekly minutes can be achieved in one or two sessions with full health benefits
- Bouts of any length now count; the 10-minute minimum rule is scrapped
- 75 minutes of vigorous activity matches 150 minutes of moderate activity
- Guidance still recommends some activity every day where possible
Adults can cram their entire recommended 150 minutes of weekly exercise into one or two sessions and still get the full health benefits, refreshed UK physical activity guidelines published on Friday (10 July) confirmed.
The UK Chief Medical Officers’ updated guidance stated that the 150 minutes of moderate to vigorous activity “can be accumulated in bouts of any length, and/or achieved in one or 2 sessions per week while still leading to health benefits”.
The finding gives official backing to so-called weekend warriors, who concentrate their exercise into Saturday and Sunday rather than spreading it across the week.
The evidence base includes recent large-scale studies on weekend warrior activity patterns, including a 2024 analysis published in Circulation linking the pattern to lower incident disease and better cardiometabolic health, and a 2025 systematic review and meta-analysis published in Public Health.
The guidance also scrapped the previous rule that activity only counted in bouts of 10 minutes or more.
Evidence now shows bouts of any length contribute to the health benefits associated with total activity volume, meaning short bursts such as stair climbs and brisk walks to the shops all count towards the weekly total.
Adults can hit the target through at least 150 minutes of moderate intensity activity such as brisk walking or cycling, 75 minutes of vigorous activity such as running, even shorter durations of very vigorous activity such as sprinting or stair climbing, or a combination of all three, according to the report.
The Chief Medical Officers said the priority is doing something rather than worrying about the schedule. “If you do no physical activity do some, and if you do some do a bit more,” the four Chief Medical Officers stated in the report’s foreword.
The guidance still recommends adults aim to be active every day where possible, and stated that spreading activity across the week can make the target easier to achieve within daily routines. Adults should also do muscle strengthening activities on at least two days a week and minimise time spent sitting, according to the guidelines.
The refreshed guidelines update the 2019 evidence base and leave the overall weekly activity targets unchanged.
