Long-term conditions comprise the biggest burden on the NHS, involving more than half of all GP consultations, 65% of out-patient visits, and 70% of inpatient bed days.1 Their prevalence rises with age, affecting 50% of people by the age of 50 years and 80% by the age of 65 years. As older people accumulate more long-term conditions, they become increasingly frail and are at higher risk of falls, disability, admission to hospital, and the need for long-term care. In order to address this burden, a revolution is needed in their primary care management. Physical capability, or ‘physical functioning’, describes an individual’s capacity to undertake physical tasks of everyday living. Care and support are needed when a person is no longer able to manage tasks such as washing, dressing, and feeding. Indeed, failure to get to the toilet on time is a frequent reason for admission to residential care.2 Maintaining physical function is one of the most important factors for quality of life among older adults and a central goal for all people with long-term conditions. Physical inactivity is one of the strongest predictors of physical disability in older people, and physically active people have better levels of physical and psychosocial functioning. Although normal ageing leads to a decline in physical fitness, this decline is much worse if a person has a sedentary occupation or lifestyle. However, the detrimental effects of prolonged sitting on mortality can be ameliorated by 60–75 minutes of moderate-intensity physical activity per day, …
