Krista Stryker, NSCA-CPT

Krista Stryker is an NSCA certified personal trainer and the founder of 12-Minute Athlete, a website providing free, incredibly effective high-intensity interval training (HIIT) workouts and awesome fitness motivation for athletes of all levels. Her approach addresses all the problems that prevent people from working out: not enough time, can’t afford a gym membership, no equipment, travel too often, or too embarrassed to work-out in front of others. She's also releasing a book that details more of this 12-Minute process, called The 12-Minute Athlete: Get Fitter, Faster, and Stronger Using HIIT and Your Bodyweight. Check out the 12-Minute Athlete HIIT Workouts app (now on both iPhone and Android!) or follow her on Twitter @12minuteathlete for more workout and fitness inspiration.
