Sprint 8 Cardio Protocol

Phil Campbell's new book, SPRINT 8 CARDIO PROTOCOL unlocks the secrets of short-burst, maximum-effort, sprint-intensity cardio so you get superior results FAST!!!

Sprint 8 Cardio Protocol shows readers sprint-intensity cardio targeting exercise-induced growth hormone to create a NEW YOU with more energy.

A new you with improved cardiovascular fitness. A new you with less body fat, more muscle and stronger bones. A new you with enhanced optimism. And a New You with better health.

Sprint 8 has been heralded in numerous publications, including Outside, Self, On Fitness Magazine, and Oprah's O Magazine, which calls Sprint 8 the fastest-working workout.

Campbell explains hospital-based research specifically on the Sprint 8 Cardio Protocol. He shows readers how to step out of a calorie-counting world of long, slow cardio (that only gets results with near-starvation dieting) into a world of results equal to and even better than injecting growth hormone and steroids -- EXCEPT Sprint 8 gets these superior results NATURALLY. And the Protocol is only 20 minutes, three-times-a-week.

In his first book; Ready, Set, Go! Fitness for Time-Crunched Adults; now in the second edition, ninth printing, Campbell explains the 10-Minute Stretching Routine, E-Lifting technique to target fast-muscle fiber during strength training. Ready, Set, GO! Fitness, is a perfect companion book for the Sprint 8 Cardio Protocol.
