What B Strong does
B Strong is a private consumer health and sports performance company founded in 2017 and headquartered in Park City, Utah, operating through the legal entity Stray Whales, LLC. The company sells a patented Blood Flow Restriction (BFR) training system built around elastic compression bands that partially restrict venous blood return during low-load exercise, eliciting strength and hypertrophy adaptations comparable to heavy resistance training. The system was co-developed by Dr. Jim Stray-Gundersen, an Olympic physician with 35+ years in sports medicine, and Sean Whalen, who serves as CEO.
The core product line consists of the Individual Pack for direct-to-consumer buyers and the Trainer Pack (8 BFR bands at $999.92) for professionals, both built on a patented multi-chamber air-baffle design (US Patents 11,395,662 and 11,207,237) engineered so that bands cannot fully occlude arterial blood flow, addressing the primary safety objection to traditional BFR cuffs. The hardware is complemented by the B Strong mobile app, which delivers personalized pressure guidance through an algorithm based on user biometrics, and by accredited BFR certification courses (BOC, NASM, NSCA, AFAA). Revenue is generated through one-time hardware sales, an annual mobile app subscription with auto-renewal, and professional certification fees.
B Strong serves four primary segments — elite athletes and professional sports organizations, fitness enthusiasts, rehabilitation and physical therapy patients, and trainers and wellness practitioners — through a Shopify-powered DTC storefront, field sales of Trainer Packs to clinics and training facilities, international shipping, and a certified ambassador network. Named customers and endorsers include Alabama Crimson Tide, WWE, Cubs, Red Sox, Warriors, Mayo Clinic, Johns Hopkins, HSS, U.S. Army, SOCOM, Mark Wahlberg, and Sarah Hendrickson.
