Interval Training for Busy Lives
Interval training fits busy schedules — short bursts of effort with rest build strength and stamina fast.

Short on time? Interval training can deliver powerful fitness benefits quickly. By alternating bursts of effort with rest, you maximise results in minimal time.
Why it works:
- Boosts cardiovascular fitness and endurance
- Burns more calories in less time
- Raises metabolism even after your workout ends
- Can be done with any activity — walking, cycling, swimming, or bodyweight
Start with short intervals (e.g. 30 seconds effort, 1 minute rest) and adjust to your fitness level. Always warm up and cool down.

- GuideTraining for an event (5K, hike, ride)Start slowly and build up at your own pace. The NHS Couch to 5K plan runs 3 times a week and can take 9 weeks or longer. For a hike, long walks are the best training. Easing off before an event is a general idea, not a strict rule.
- GuideVariety and cross-trainingMixing activities is a sensible habit, but it isn't clear yet that it prevents overuse injuries in inactive adults. Build up slowly, keep some lighter days, and when exercise gets boring, change one thing and choose activity you enjoy.
- GuideMaking your health a priorityStart with a small amount of activity you can manage this week, plan when you'll do it, and protect that time kindly but firmly. Ask family and friends for one specific kind of support. The biggest health gains come from the first steps, and staying active over the years adds more.
- GuideMixing cardio, strength, balance and flexibilityA balanced week combines aerobic activity such as walking with muscle-strengthening on at least 2 days, with balance and flexibility work alongside. You don't need all four at once: doing less than the targets still helps, so add one kind at a time.
- GuideBuilding a weekly routineStart with an amount of activity you can manage now, then choose the days, times and places for the week ahead. Build towards about 150–300 minutes of moderate activity a week plus strength exercises on two days, and treat your plan as a flexible draft you can change.
- GuideFinding timeYou can fit activity into a busy week by planning when, where and how, using short bursts, and building it around things you already do. Activity of any length counts, and the time of day matters less than doing it regularly. Start small and build up gradually.
