Running across life: women, older runners and chronic conditions
Most adults share the same aerobic and strength targets, but pregnancy and postpartum, older age and chronic conditions require individual context. Build safety and consistency before pace and performance.
Contents
The guidelines apply to most adults
The CDC recommends at least 150 minutes of moderate-intensity aerobic activity a week, or an equivalent amount of vigorous activity, plus muscle-strengthening activity on at least two days a week. Activity can be spread across the week, and some activity is better than none.
These are population minimums, not race plans. Running is one form of aerobic activity. If you are starting, returning or managing a health issue, begin with an amount you can repeat consistently and build from there.
Women, pregnancy and postpartum
Women runners follow the same basic aerobic and strength guidance as men. Pregnancy and postpartum are special phases: the CDC states that physical activity is healthy and safe for most pregnant women, and healthy pregnant or postpartum women need at least 150 minutes of moderate-intensity activity a week. Each person should discuss activity restrictions with their maternity or postpartum clinician.
Postpartum recovery varies widely and should not be rushed to match social-media timelines. Pelvic-floor symptoms, persistent bleeding, wound problems, dizziness or pain deserve medical assessment. Before returning to running, check that daily activity and strength foundations are stable.
Older runners
CDC guidance for adults 65 and older includes aerobic activity, muscle strengthening and activities that improve balance. Age alone is not a reason to stop running, but balance, bone health, medication, previous injury and recovery speed belong in the plan.
Older runners benefit more from strength, balance and gradual loading than from comparing pace with younger runners. Stop and seek medical advice for falls, chest symptoms, unusual breathlessness, dizziness or new pain.
Chronic conditions and medication
The CDC notes that adults with chronic health conditions or disabilities can be active and gain health benefits. When able, the target is still at least 150 minutes of moderate aerobic activity a week plus two days of muscle strengthening; some activity is better than none.
The details depend on the condition, medication and day-to-day state. Some medicines affect heart rate, temperature regulation or blood glucose; heat, dehydration and infection can raise risk. Discuss appropriate intensity and monitoring with a clinician who knows your condition, and do not change medication on your own.
What this page does not provide
This page does not diagnose disease, prescribe individual exercise for pregnancy or chronic conditions, or replace maternity, cardiology, endocrinology or other specialist care. Chest pain, fainting, severe breathlessness, altered consciousness, persistent bleeding or marked deterioration need urgent medical help.
Sources and scope
Adult, older-adult and chronic-condition guidance follows CDC activity pages; pregnancy activity and weight information follows CDC maternal-health guidance. This page provides general principles; restrictions should be judged by a professional who knows your health situation.
Sources and evidence
Adults aged 65 and older need aerobic, muscle-strengthening and balance activities each week. The aerobic target is at least 150 minutes at moderate intensity, 75 minutes at vigorous intensity, or an equivalent combination. Older adults need at least two days of muscle-strengthening activity and activities that improve balance. People benefit from physical activity throughout life, including as they age.
Adults with chronic health conditions or disabilities can be physically active and gain important health benefits. Adults with chronic conditions or disabilities who are able should get at least 150 minutes of moderate-intensity aerobic activity a week and at least two days of muscle-strengthening activity. Some physical activity is better than none; people should be as active as they are able. Regular activity can improve function, sleep, mental health and cardiovascular health for people with chronic conditions.
Healthy pregnant or postpartum women need at least 150 minutes of moderate-intensity aerobic activity per week. Weight is influenced by factors including sleep, age, genes and medications. People who are physically active can still gain weight if they take in more calories than they use. A health care provider is the best person to ask whether illnesses or medications are contributing to weight gain or making weight loss difficult.
Physical activity is healthy and safe for most pregnant women. Pregnant women should talk to their health care provider about any physical activity restrictions. Work up to or maintain at least 150 minutes of moderate-intensity aerobic activity per week, which can be broken into smaller chunks. Pregnancy weight-gain goals should be discussed with a health care provider.
