About 8 Weeks Out

I founded 8weekout in the spring of 2009 for one simple reason:
To cut through all the clutter and misinformation surrounding strength, conditioning, combat sports and performance

Too many people were looking for answers, but getting lost amidst the endless sea of hype and bad information. There needed to be a voice of reason that came from experience and a solid foundation of scientific understanding. After more than 5years of training world class combat athletes at the time, I wanted to share the training principles, methods, and philosophy that I had used to help develop world champions and top athletes from a range of sports.

Since its beginnings, 8weeksout has expanded to cover all areas of fitness and physical preparation for athletic performance. I have brought together a world renowned team of experts ranging from NFL coaches to PhD researchers, all united in the pursuit of finding and sharing the truth about how to push the human body to the highest levels.

The 8WeeksOut mission is to deliver the truth about training and athletic development with honesty, integrity, and real science rather than marketing hype and baseless claims.

I am committed to building a community of experts, athletes, and recreational fitness enthusiasts who are looking for something more and who are striving to find the answers of human performance that often allude so many. Every single contributor to this site meets the high standards I have set for passion and integrity in this field and you can trust the information you will find on this site comes from authority, experience, and scientific reasoning.

Thanks for visiting 8WeeksOut!
