The secret is out: training constantly varied functional movements executed at high intensity creates incredible levels of fitness. But the explosive growth in popularity of CVFMHI training is sometimes problematic. Neophyte trainers can find themselves in over their heads when teaching complex skills to groups of varying ability, and trainees, lacking clear exercise progressions, may attempt movements they're not ready for. The result? Poor form, bad habits, and all too often, injury.

That's why I created By the Numbers. BtN is a system for instructing CVFMHI that emphasizes progression at every level. It builds exercises pose-by-pose, movement skill exercise by exercise, and work capacity--fitness--by testing movement skill with incremental increases in volume, load, and intensity. And it's effective whether you're coaching one-on-one, or leading a class with dozens of athletes.

By the Numbers: A Practical Method for Instructing Constantly Varied Functional Movements Executed at High Intensity is my attempt to distill seven years of full-time coaching experience into a manual new trainers can use to bridge the gap between what they know when they emerge from their Level 1 certification, and what they need to know to run a safe and effective CVFMHI program.

By the Numbers is all about creating the best moving general population gyms in the world. Want yours to be one of them? Start teaching BY THE NUMBERS today!
