Tough Mudder, the obstacle course series, is partnering with Openfit, a new digital streaming platform for integrated fitness, nutrition, and wellness, to create Tough Mudder T-Minus 30, a 30-day fitness and nutrition program to prepare participants for the challenges of a Tough Mudder event, and to help users in general break personal barriers. T-Minus 30 is described as the first comprehensive obstacle-course-focused workout program on the market. The 30-day program includes workout sessions that strengthen specific muscle groups and improve physical fitness in terms of power, endurance, core strength and mobility. Users are put to the test in the fourth and final week of the program, named “Challenge Week,” with specialized workouts created to simulate a Tough Mudder event. Tough Mudder T-Minus 30 is available exclusively to Openfit subscribers on and on Android, iOS and Roku devices.
