AI Fitness Advice Widely Used but Distrusted, Experts Warn of Injury Risk

TL;DR: Most Americans and Britons use AI regularly, yet few trust it, and experts warn that AI-generated fitness plans can be inaccurate and lead to injury.

Despite widespread adoption, confidence in artificial intelligence remains low across the Atlantic. Surveys show 62% of people in the United States and 69% in the United Kingdom use AI on a regular basis. However, only 26% of Americans view AI positively, while 78% of Britons express concern about negative outcomes from the technology.

These figures come from cross‑sectional polling, which reveals a correlation between usage and distrust but does not prove that one causes the other. No randomized trials have yet examined whether AI‑generated workout advice directly increases injury rates; current evidence remains observational.

Dr Carol Garber, professor of movement science and education at Columbia University, cautions that AI offers only a “cookbook” approach to fitness and often supplies incorrect information. She warns that such errors could result in serious injuries and recommends verifying any AI‑generated plan with credible sources or, preferably, a certified exercise professional.

For readers who choose to use AI for fitness guidance, practical steps include cross‑checking exercise prescriptions with reputable guidelines, starting with low‑intensity routines, and seeking feedback from a qualified trainer when possible. Treat AI as a supplemental tool rather than a sole authority on workout design.

Researchers are expected to launch controlled studies in the coming year to assess injury outcomes linked to AI‑driven exercise programs, which will clarify whether the observed associations reflect causal risks.
