THE TEAM BEHIND THE WORK
BUILT BY PHDS AND THOSE WHO HAVE DONE IT.

DR. CHARLIE
Head Strength & Conditioning Coach
PhD Human Performance
Master's, Kinesiology & Exercise Science – Sport Performance
Certified Strength & Conditioning Specialist (CSCS)
Dr. Charlie Ottinger is one of several PhDs on the Blue / Green team and leads our strength and conditioning work. He is an Assistant Professor of Exercise Science at Barton College and previously served as Director of Human Performance & Sport Science at the Applied Science & Performance Institute. He is a strength and conditioning coach and competitive powerlifter.
Most training programs are built by one side or the other: coaches without the military context, or operators without the performance science. Since 2023, Dr. Charlie has enabled Blue / Green to bridge that gap, pairing his expertise in human performance with the team's deep conventional and SOF experience. The result is what thousands of athletes have used to prepare for, and succeed at, Ranger School, SFAS, SFQC, Sapper School, and BOLC, while helping seasoned professionals keep climbing.

HAVE QUESTIONS
Common Questions.
Most military fitness brands sell you a spreadsheet of workouts. Cookie cutter programs with no explanations and no way to adjust. Some do take it beyond that, but rely on what worked for them, rather than what is proven in exercise science. Generic and unproven isn't what you're going for.
For more than 5 years, B/G has been leveraging the experience and context of seasoned military professionals with the expertise of PhDs in exercise science, nutrition, and mental performance. Together, the material helps you reach your full potential. We offer guides, not workout spreadsheets.
This isn't built for everyone, and we're not trying to be. If you want easy, easy is available everywhere. If you want simple, simple is cheaper to find. If you want needlessly expensive, you can find a 1:1 offering pretending to be custom to you.
Blue / Green is for the soldier who already knows he's capable of more than his current situation reflects and is finally ready to act on it.
Far more than workouts. Blue / Green guides covers the four domains your performance actually depends on including fitness, nutrition, mental skills, and recovery. This is written by PhDs in each of those fields alongside those with rich military experience across SOF and conventional forces. Together, you get an expert point of view that is relevant you.
What you're buying isn't a workout plan. It's everything that has to be in place for the workouts to actually transfer to performance.
Every customer gets direct email access to our team for questions about programming, nutrition, recovery, or anything else that comes up. When you need something, send us a DM and we’ll be ready to help make it work for your unique situation.
