Exercise During Chemotherapy: — What Is Safe?

Most people rest during and immediately after the infusion itself. The day after, many find a short gentle walk manageable if they feel well enough. Let how you feel be the guide. If you are unsure whether activity on a specific day is right for your situation, ask your team at your next appointment — they know your treatment schedule and can give you a specific answer.

Walking is the best-supported starting point. It is low impact, requires no equipment, and can be adjusted to how you feel moment to moment. Gentle stretching and light household movement also count. Most guidance recommends avoiding high-intensity exercise and activities that risk injury or infection — particularly if your immune system is suppressed. A physiotherapist can help you build beyond walking when you are ready.

You generally will not know your counts on a given day unless your team has just tested them. Ask at each infusion appointment whether your counts are at a level where you should keep still on any particular days. If your team flags low platelets or very low neutrophils, treat that as a rest day. When counts are not flagged as a concern, gentle movement between cycles is usually appropriate.

Cancer-related fatigue is different from ordinary tiredness and does not always improve with rest alone. ASCO and ESMO both note that physical activity reduces cancer-related fatigue more effectively than rest in most people. Start very small — even a few minutes of walking — and build only when that feels manageable. If your fatigue is severe or not improving, tell your oncologist. Sometimes fatigue has a treatable cause such as anaemia.

Probably not at the same intensity, but not stopping completely either. Most people find their capacity decreases during treatment and need to adjust what they do and how hard they push. Continuing some movement — even much lighter than before — is better for fatigue and mood than stopping entirely. Ask your oncologist about a physiotherapy referral to help you set realistic targets for your treatment period. You can rebuild intensity afterwards.
