Dr. Sarah Okafor

About

Dr. Sarah Okafor holds a PhD in Exercise Physiology from the University of Texas and spent five years running clinical trials on metabolic adaptation before becoming a full-time fitness writer. She bridges the gap between peer-reviewed research and the gym floor — evidence-first but deeply practical. She trains herself (powerlifting and zone 2 cardio) and has zero patience for marketing-driven fitness claims. Every recommendation she publishes is backed by specific studies, sample sizes, and effect sizes.
