When it comes to how often to workout for longevity, the experts agree that some movement is always better than none. That said, the NHS guidelines are a good place to start. “The NHS guidelines state strength training for all major muscle groups 2 days a week and 150 minutes of moderate intensity exercise (or 75 mins of vigorous intensity exercise) a week," says Parkinson. "I always advise my clients to do these as a minimum and aim to reduce long periods of inactivity as much as they can. Even short bursts of walking can make a huge difference both mentally and physically. It's also important for longevity to ensure you get enough rest too so that the body recovers appropriately. Spreading workouts out and prioritising sleep, hydration and rest time is crucial for long-term well-being."
