CrossFit for cancer survivors: a new way to reclaim strength?
NCT ID NCT03750981
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether a 12-week high-intensity functional training program, like CrossFit, can improve movement, body composition, and quality of life in cancer survivors. Researchers will enroll 500 adult cancer survivors who have been cleared by their doctor. The goal is to see if this type of exercise works better than standard recommendations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- high-intensity functional training (CrossFit)
- What this could lead to
- If it works, this could offer cancer survivors a practical exercise program to improve strength, flexibility, and overall well-being.
- What could go wrong
- This is an early pilot study with no control group, so results may not be definitive. The intense exercise may be too challenging for some survivors, and participation is limited to those who can travel to specific gyms.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged 18 years or older at time of program recruitment * Diagnosed with any cancer * Cleared from their physician to participate in the program (We assume that most patients will have completed treatment, however if a patient is currently under treatment, this should be their oncologist. If the patient is not currently undergoing treatment, this could be primary care physician or oncologist). * Available transportation to and from the facility on session days Exclusion Criteria * Widely metastatic cancers to the brain or bone may be excluded. * Patients using mobility assistance devices may be excluded. Exclusionary criteria will be reviewed on a case-by-case basis and patients with these limitations may be included with approval from Dr. Beebe-Dimmer and the referring physician.
