Review: Intense and extensive

This workout is extensive covering aerobic/ cardio workout. Four weeks is good as a person would have to start slowly or with less reps unless he/she is ready for it. Good and concise, well expressed with photos. These routines, I believe, are for young to middle aged: late teens to late 40s age groups.
