1-Minute HIIT is a 30-day no-equipment high intensity interval training program with short and to-the-point workouts designed to lose fat and streamline and suitable for all fitness levels. Each day consists of a 1-minute-long circuit followed by a 1-minute break you repeat several times depending on your fitness level and/or the time available.
The program primarily focuses on burning fat but it also includes additional ab-work and strength-oriented exercises.
Additional instructions: Work in bursts at 100% effort and go flat out every single time. Take no rest in between.
