What do Cristiano Ronaldo, LeBron James... and astronauts have in common? They’re all using the same training technology, blood flow restriction (BFR).
In this episode, host Richard Graves back Dr. Warren Bradley, Chief Science Officer and founder of Hytro, to unpack how BFR is transforming the way athletes train, recover, and even how astronauts prepare for life in space.
You’ll learn:
What blood flow restriction actually is, and how it helps build strength, muscle, and endurance faster (with less load on your body).
Why BFR is no longer just for injury rehab, and how pro athletes are using it to boost performance and speed up recovery.
The science behind why restricting blood flow (safely!) creates powerful training adaptations.
How Warren’s product ended up on a SpaceX rocket, and why NASA now uses BFR to fight muscle loss in space.
Common myths and misconceptions about BFR… including whether it’s safe (spoiler: it is, with the right approach).
Where BFR is heading next, from grassroots athletes to medical rehab and even everyday gym-goers.
Warren also shares his incredible journey, from working in the Premier League to founding a company used by over 260 elite teams worldwide, all the way to collaborating with NASA for space missions.
This is one of those episodes that blends cutting-edge science with real-world application. Whether you're a coach, athlete, or just a performance fanatic, this one’s a must-listen.
