Last July Scott Douglas wrote about Matt Tegenkamp’s core routine for RunnersWorld.com. The article was one of the most-viewed stories of the summer. This winter the editors at Runner’s World asked if Matt would highlight certain aspects of the routine on video. The result is this four-part series, which has already been viewed over 30,000 times.
Part I: The Warm-Up
Part II: Floor Routine
Part III: Dumbbell Routine
Part IV: Balance & Glute Routine
