Exercise during cancer recovery is evidence-based medicine. The ACSM says so. Your oncologist may have told you so. But finding a coach who actually understands fatigue management, treatment interactions, and graduated return protocols — that has been nearly impossible. Until now.
This is non-negotiable. Body by AI requires oncologist or treating physician clearance before starting any exercise program. If you are currently in active treatment, clearance is required at every stage change. We work with your medical team — not around them.
The evidence is unambiguous. The challenge is finding someone who can actually coach it safely.
Cancer-related fatigue (CRF) is not the same as being tired after a hard workout. It does not resolve with rest. It can be caused by treatment, anemia, pain, emotional distress, or the cancer itself — and each source requires a different response.
Some days, zero exercise is the correct prescription. Body by AI recognizes when you report high fatigue and responds with rest, gentle movement, or abbreviated sessions — not "push through it."
Body by AI reads your fatigue reports and adjusts — including to zero — every session.
High-dose antioxidants (Vitamins C and E, beta-carotene) have been shown in RCTs to reduce chemotherapy efficacy. Some supplements interact with common oncology medications. The evidence on supplementation during treatment is not neutral — it is actively cautionary.
Body by AI does not recommend supplements during active treatment. Period. Nutritional guidance focuses on whole food sources, adequate protein for muscle preservation, and anti-inflammatory eating — nothing that could compromise your treatment.
No supplement recommendations during active treatment. This is an absolute rule.
Completing treatment is not the same as recovering from treatment. Chemotherapy, radiation, and surgery have lasting physiological effects — cardiac changes, peripheral neuropathy, bone density loss, lymphedema risk — that require informed coaching, not generic programming.
The return-to-activity protocol used by Body by AI for post-treatment survivors is built on ACSM's exercise oncology position stands — the most rigorous guidelines available.
Body by AI follows ACSM exercise oncology guidelines for post-treatment programming.
Every element is calibrated to your current treatment phase — in treatment, immediately post-treatment, or long-term survivorship. The program shifts as you do.
Treatment-phase awareness
The program knows whether you are in active treatment, in the immediate recovery window, or in long-term survivorship. Programming, intensity, and recovery expectations differ at each stage.
Cancer-related fatigue management
Every session begins with a fatigue check. High fatigue days get abbreviated sessions or rest. The system never pushes you into intensity that your body is not currently able to handle.
No supplements during treatment
Supplement recommendations are suppressed entirely during active treatment. Nutritional guidance focuses on whole foods, anti-inflammatory eating, and adequate protein from food sources only.
Lymphedema-aware exercise selection
For survivors with lymphedema risk (particularly breast cancer survivors), Body by AI avoids high-repetition, high-load arm exercises and provides compression garment reminders for at-risk activities.
Peripheral neuropathy modifications
Chemotherapy-induced peripheral neuropathy affects balance and sensation. Programming includes balance-first progressions and avoids exercises that require fine sensory feedback in affected limbs.
Oncologist coordination ready
Body by AI generates session summaries you can share directly with your oncology team. Your medical team stays informed. You stay safe.
Most personal trainers will not work with cancer patients — either because they lack the knowledge or because they are concerned about liability. Most fitness apps simply have no cancer pathway at all. The result is that one of the populations that would benefit most from structured exercise gets left out entirely.
The evidence for exercise during and after cancer treatment is strong. Reduced fatigue, improved treatment tolerance, better cardiovascular outcomes, lower recurrence risk in several cancer types, improved quality of life — the research is not ambiguous. The gap is not in the evidence. It is in the coaching.
Body by AI was built to close that gap. The populations that need coaching the most are the ones that existing solutions serve the worst.
