6M subs. 3D muscle animation explainers. Best exercise series 200M+ views. Wearable app integration.
Jeremy Ethier built 6M subscribers by presenting training research visually — 3D muscle animations, EMG studies, and before/after case studies that make sports science accessible to everyday lifters. His "best exercises for each muscle" series (biceps, chest, back, shoulders) consistently rank #1 in search and have been watched 200M+ times collectively. In 2026, Built with Science's app integrations with wearables make him one of the few YouTube creators with a direct training tool pipeline.
