Exercise for Kidney Disease: A Safe Guide for CKD, Dialysis and Transplant

Is exercise good for chronic kidney disease?

Yes. The KDIGO 2024 guideline, the main international guideline for CKD care, recommends that people with CKD do moderate physical activity for a total of at least 150 minutes a week, or as much as their heart and physical condition allow. The NIDDK gives a similar target: be active for 30 minutes or more on most days.

The NHS says exercise is good for anyone with kidney disease, however severe. People with mild to moderate CKD can usually exercise as much as other people their age. People with more advanced CKD, or on dialysis, may tire or get out of breath sooner, but they still benefit. The key is to start slowly and build up.

A Cochrane review found that regular exercise in people on dialysis likely improves physical function and probably eases symptoms of depression. Being active also helps you keep the strength you need for daily life, such as climbing stairs and getting out of a chair.

Exercise and blood pressure in kidney disease

The NIDDK calls blood pressure control the most important step you can take to treat kidney disease. Regular activity is one of the ways to help reach your blood pressure goal, along with medicine, heart-healthy eating, sleep and not smoking. Your doctor will set your personal target.

Avoid holding your breath when you lift or push, because straining can raise blood pressure sharply. Breathe out on the effort. If your blood pressure medicine makes you dizzy when you stand up, rise slowly and cool down gradually at the end of each session.

Exercising on dialysis: timing, fistula care and fluid limits

Many people feel tired for hours after a hemodialysis session. The NIDDK notes that some people need to rest afterward. For that reason, most people find it easier to exercise on non-dialysis days, or before a session if they feel well. Avoid hard exercise right after treatment, when blood pressure can be low.

Some dialysis units offer pedal bikes or simple exercises you can do in the chair during treatment. This is called intradialytic exercise, and it is done under staff supervision. Ask your dialysis team whether your unit offers it.

• Fistula or graft arm: keep it free of tight straps, heavy loads and pressure. Ask your team how much you can lift with that arm. The NIDDK advises checking your access every day and telling your center if you cannot feel the usual vibration.
• Fluid limits: follow the fluid limit your team gave you, even when you exercise. Do not drink extra just because you are active. Exercise in a cool place and pick a lower intensity on hot days, so you sweat and feel thirsty less.
• Peritoneal dialysis: the NIDDK says you can still be active and play sports, but you may need to limit some activities while dialysis fluid is in your belly. Ask your team which exercises are safe, and protect your catheter site.

Best exercises for kidney disease

Low-impact aerobic exercise is the best place to start. Walking, a stationary bike, swimming (if your team says it is safe for your access) and water aerobics all work your heart without much strain on your joints. Aim for a moderate effort, where you breathe harder but can still talk in full sentences.

Strength training 2 times a week helps you keep muscle, which CKD and dialysis can wear away. Use light weights, resistance bands or your own body weight. Balance and stretching moves help prevent falls, especially if you feel weak or dizzy at times.

• Aerobic: walking, stationary bike, water aerobics, dancing.
• Leg strength: sit-to-stands from a chair, heel raises holding a counter, step-ups on a low stair.
• Arm strength: band rows, light bicep curls and wall push-ups. Use only your non-access arm for weights if you have a fistula or graft, unless your team says otherwise.
• Balance and flexibility: standing on one leg near a counter, gentle stretching, chair yoga or tai chi.
• Start with 1 set of 8 to 12 repetitions and breathe out on the effort.

How to start when you feel tired

Fatigue is common with CKD. It can come from anemia, poor sleep, dialysis or low fitness. Tell your doctor about it, because some causes can be treated. Gentle exercise often helps energy over time, but it needs to start small.

Short bouts count. Two or three 5 to 10 minute walks spread over the day can be easier than one long session. Increase one thing at a time: how long, how often, or how hard. If you feel wiped out the next day, stay at the same level for another week. VitalStep can build a personalized, low-impact plan that progresses at a pace like this.

• Weeks 1-2: 5 to 10 minutes of easy walking or cycling on 3 to 5 days, plus one short strength session.
• Weeks 3-4: 10 to 15 minutes per session. Strength twice a week.
• Weeks 5-8: build toward 20 to 30 minutes on most days, as your energy and your care team allow.

Exercise after a kidney transplant

Most people can become more active after a kidney transplant once they recover from surgery. In the first weeks, your transplant team will tell you when you can start walking and when you can lift, drive or return to sport. Avoid heavy lifting and strain on your belly until your incision has healed and your team clears you.

Once you are cleared, the same approach applies: low-impact activity most days and strength training twice a week. Staying active can help with weight gain and blood pressure, which are common after a transplant.

When not to exercise with kidney disease

Skip exercise and contact your care team if you have a fever, an infection, or signs of fluid overload such as new swelling in your legs, sudden weight gain or shortness of breath when lying down. Also skip it if you missed a dialysis session, or if your team told you your potassium or blood pressure is out of range.

Restart gently once you feel better, at about half of what you were doing before, and build back up over a week or two.
