SKOGG System, presented by Michael Skogg, is a 5 DVD set. It contains one instructional DVD and 4 workout DVDs. Each workout has 4 different levels, so anyone from a novice to a warrior can tailor the workout to fit their fitness and ability level. The workouts vary in length from 10 minutes to 35 minutes, the higher the level the longer the workout. In addition, each workout begins with a warm up and ends with a cool down/stretch.
