Before BodyCircuit, Brian Leddy spent 15 years as a media executive. High performance, high stress, and a body that was quietly falling apart. He didn't find a program that worked — so he built one.
Formerly an Adweek executive and media entrepreneur, Brian spent 15 years building businesses and managing high-stakes careers. But by his mid-30s, something was off — chronic stress, low energy, skin issues, and steady muscle loss. He was performing at work and deteriorating everywhere else.
In January 2023, he decided to fix it. He researched over 100 programs, tried everything — vegan, carnivore, cold plunges, fasting, energy supplements. What he found was a never-ending loop of conflicting advice that left him more confused and burnt out than before.
Eventually he found the Functional Diagnostic Nutrition certification — real data, real protocols, real personalization. He went through the same testing and health protocols he now uses with clients. The clarity it gave him changed everything. He went on to earn additional certifications in fitness, movement, and nutrition — and BodyCircuit was born.
Optimal health is personal. What works for one person may not work for another. That's why Brian blends data, coaching, and flexibility into everything at BodyCircuit — and why the approach keeps evolving as the science evolves.
Heavily influenced by notable experts including Dr. Layne Norton, Dr. Peter Attia, Dr. Idz, Dr. Stacey Sims, Judd Lienhard, and Dr. Joey Muñoz — Brian understands deeply that the best system is the one built around your biology, not someone else's.
These days Brian feels better than he has in years. The goal is the same for every BodyCircuit client.
Every certification Brian holds was chosen because it directly improves client outcomes — not to collect letters after a name.
When Brian's not coaching clients or digging into the latest performance research, you'll find him coaching youth basketball at the local church, chasing a frisbee around town, or competing on the pickleball court. He's a husband, dad of two, and a genuine product of everything he teaches.
Follow Brian on Instagram for his latest performance recommendations, training updates, and the occasional pickleball highlight.
The 14-day onboarding experience gives you everything you need to build momentum — with Brian in your corner from day one.
