How many days a week should you exercise in midlife and beyond?

1. The NHS and WHO recommend 150 minutes of moderate aerobic activity, two or more strength sessions, and two or more balance sessions per week for older adults. That is the minimum, not the optimum. 2. Recovery capacity declines with age. Sensible training frequency has to account for sleep quality, stress levels and how quickly you personally bounce back. 3. The best number of training days varies from person to person. Adjusting week by week, based on how your body responds, beats following a fixed schedule.

The NHS physical activity guidelines for older adults recommend at least 150 minutes of moderate intensity aerobic activity per week (or 75 minutes of vigorous activity), strength exercises on two or more days, and balance and coordination work on at least two days (NHS, 2019). The World Health Organisation guidelines align with this and add that older adults with chronic conditions should be as physically active as their abilities allow (WHO, 2020). These are well supported. A 2022 meta-analysis in the British Journal of Sports Medicine found that meeting the WHO guidelines was associated with a 31 percent reduction in all-cause mortality, a 29 percent reduction in cardiovascular mortality and a 15 percent reduction in cancer mortality (Garcia-Hermoso et al., 2022).

The guidelines tell you the minimum. They do not tell you the ceiling. And as you get older, the ceiling matters, because recovery capacity changes. A session that needed 24 hours of recovery in your thirties may need 48 to 72 hours later on. This is driven by hormonal changes: declining growth hormone, reduced testosterone in men, and the effects of menopause in women all slow muscle repair and tissue recovery. A 2013 study in the Journal of Clinical Endocrinology and Metabolism found that just two weeks of reduced activity in older adults caused muscle loss equivalent to 40 years of normal ageing (Breen et al., 2013). The flip side is also true: training too often without enough recovery leads to accumulated fatigue, raised cortisol, disrupted sleep and more injuries. In practice, people who arrive training five or six days a week and feeling terrible often do far better on three well-programmed sessions with proper recovery between them - stronger, sleeping better, and no longer picking up injuries.

There is no universal answer, but there are factors that decide what is right for you now. Sleep quality. Poor sleep impairs muscle protein synthesis and raises cortisol. A study in Sports Medicine found that sleep deprivation reduced exercise performance by 11 to 20 percent and significantly impaired recovery (Fullagar et al., 2015). If you are sleeping fewer than six hours a night, adding training days will not help. Fixing your sleep will. Stress levels. Chronic psychological stress elevates cortisol, which competes directly with the hormonal environment needed for recovery. A 2014 review in Sports Medicine found that high perceived stress reduced post-exercise recovery rates by 25 percent (Stults-Kolehmainen and Sinha, 2014). During stressful periods, fewer sessions at lower intensity often produce better results. Training history. If you have been sedentary for years, two sessions a week is a real stimulus. If you have trained consistently for decades, three or four may suit you. The body adapts to what it knows. Existing conditions. Osteoarthritis, chronic pain, post-surgical recovery and autoimmune conditions all affect how much training you can tolerate, and need to be considered individually.

For many people in reasonable health moving through midlife, an evidence-based starting point looks like this: Two to three strength sessions per week, each 45 to 60 minutes, with at least 48 hours between sessions targeting the same muscle groups. One to two Pilates or mobility sessions per week, focusing on balance, proprioception and movement quality. Daily walking of 20 to 40 minutes, which covers much of the aerobic component. One recovery session per week, such as therapeutic massage, to look after tissue health and the nervous system. That totals four to six structured sessions plus daily walking - but the exact split depends on your body.

At Sway, your programme is not fixed. It adjusts week by week, because the person writing it knows you. You work with one dedicated coach, qualified in both Pilates and Strength and Conditioning, who trains you in your home across London or live online. Because the same coach sees you each week, they can read how you are responding - if your sleep has been poor, the strength session is dialled back; if you are recovering from illness, the plan shifts to mobility and light movement until you are ready. When something outside training is the limiting factor - nutrition that is not supporting recovery, persistent stress, or a niggle that needs clinical eyes - your coach can introduce you to a trusted, independent specialist from a vetted referral network. The aim is simple: match the number of sessions to what your body can actually absorb, rather than chasing a number on a guideline.

Start by asking yourself three questions. How well am I sleeping? How stressed am I right now? When did I last feel genuinely recovered after a session? If your sleep is poor and your stress is high, more training will not help. Begin with two well-structured sessions a week and build only when your recovery supports it. If you are currently doing nothing, two sessions a week is enough to produce measurable results within eight weeks - a finding backed by a 2009 Cochrane review of 121 trials (Liu and Latham, 2009). Start where you are, not where you think you should be. If you would like a clear plan built around your recovery, we offer a free assessment in your home in London or online.
