For adults aged 65 and over, WHO recommends at least 150–300 minutes of moderate-intensity aerobic physical activity per week, or at least 75–150 minutes of vigorous-intensity activity, or an equivalent combination, together with muscle-strengthening activities on at least two days each week. Older adults should also incorporate varied multicomponent physical activity that emphasises functional balance and strength, particularly where mobility is poor, with balance-focused activity recommended on at least three days per week for people with poor mobility.
NHS guidance similarly recommends older adults be physically active every day, undertake strength, balance and flexibility activities on at least two days a week, and aim for at least 150 minutes of moderate activity or 75 minutes of vigorous activity where appropriate. These recommendations are broadly similar to adult recommendations but place greater emphasis on maintaining functional capacity, balance and independence.
The most important difference for older adults is that exercise should address function as well as cardiovascular fitness. Ageing can be associated with reductions in muscle mass, strength, bone density, reaction speed and balance, although the magnitude of change varies substantially among individuals. Strength and balance training can help maintain the ability to climb stairs, rise from a chair, carry objects, walk safely and respond to disturbances in balance.
Functional exercises can include repeated chair rises, step-ups, supported squats, resistance-band exercises, weight training and balance drills appropriate to ability. These activities should be progressive but safe. An older adult who is already active may tolerate substantial training, while someone who has been inactive or has significant mobility impairment may need a much more gradual starting point.
Aerobic activity remains important because cardiovascular disease and other chronic conditions become more common with age, but aerobic training does not have to mean running. Brisk walking, cycling, swimming, water exercise, dancing and other activities can raise cardiovascular demand. The correct intensity depends on fitness and medical circumstances. A person with reduced mobility may achieve substantial benefit from adapted movement or seated exercise even if they cannot perform conventional walking or running.
WHO emphasises that people who cannot meet the recommended amount because of health conditions should be as physically active as their abilities and conditions allow. This principle prevents the guidelines from becoming an all-or-nothing test. Moving safely for a smaller amount can still be valuable, and progression can occur as capacity improves.
Strength training is particularly relevant because muscle weakness can reduce independence and increase difficulty with everyday tasks. Resistance can be provided through free weights, machines, resistance bands, bodyweight movements or functional tasks. The appropriate resistance should be sufficient to challenge the muscles while allowing safe technique and controlled movement. Older adults do not automatically need extremely light exercise: people who are already conditioned may benefit from appropriately challenging resistance training.
However, the programme should account for osteoporosis, arthritis, cardiovascular disease, joint replacements, neurological conditions and other individual factors. The objective is progressive improvement or preservation of strength rather than maximal lifting. Where an older person has substantial frailty, a physiotherapist, exercise professional with appropriate qualifications or healthcare professional can help establish a safe starting programme.
Balance training is important because falls can produce serious injury, loss of confidence, reduced mobility and prolonged dependence. Activities designed to improve balance can include standing on one leg with appropriate support, controlled changes of direction, heel-to-toe walking, Tai Chi and functional exercises that challenge postural control. NHS guidance specifically recommends strength, balance and flexibility activities at least two days a week and highlights their relevance for people concerned about falls.
Balance training should be performed in a safe environment, particularly for someone with previous falls or substantial instability. Holding a stable support or having another person nearby may be appropriate during early practice. The aim is not to create unnecessary instability but to progressively challenge the systems responsible for maintaining safe posture and movement.
Flexibility and mobility work can complement strength and balance training. Maintaining joint range of motion can make activities such as dressing, reaching, turning and walking easier, although flexibility itself is not identical to mobility or strength. Gentle stretching can be useful where appropriate, while active mobility exercises can integrate range of motion with muscular control. Older adults should also avoid prolonged uninterrupted sedentary periods.
NHS guidance advises reducing time spent sitting or lying down and breaking up long periods without movement. Everyday movement such as household tasks, walking for transport, gardening and shopping can therefore contribute to overall activity. This is particularly important for people who find formal exercise intimidating because meaningful movement can be integrated into ordinary routines.
Older adults with chronic conditions or disabilities should not assume that age or diagnosis automatically rules out exercise. WHO explicitly includes people with chronic conditions and disabilities within its physical-activity recommendations, while recognising that activities may need to be adapted. Medical advice may be appropriate when there is unstable cardiovascular disease, significant neurological impairment, severe musculoskeletal limitation or another condition affecting exercise safety.
Someone who has fallen, experiences unexplained dizziness, develops chest pain or has significant exercise intolerance should seek appropriate clinical assessment. Exercise programmes should also consider medications that influence heart rate, blood pressure, balance or alertness. The objective is to maximise safe functional capacity rather than simply achieving a numerical activity target regardless of circumstances.
For older adults, the practical framework is therefore at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week, plus strength training at least twice weekly, with additional balance-focused activity for people with poor mobility and daily opportunities for movement where possible. WHO allows up to or beyond 300 minutes of moderate activity for additional benefits when appropriate, but the correct programme depends on current capacity, medical status and goals.
A previously inactive person should start with manageable activity and progress gradually. An already active older adult can train more extensively if recovery and health permit. The most important outcomes are not simply the number of minutes but preserved strength, cardiovascular capacity, balance, mobility, independence and participation in everyday life.
