It is designed to burn fat by working big muscle groups with HIIT Training (High Intensity Interval Training) to gain quick results and will help to create a lean and functionally strong body! The idea is that you work flat out for this length of time at 100% effort! That means your 100% effort and no one elses.
It is a quick and precise method of exercise which is over as quick as it started and carries on burning fat for up to 24 hours afterwards!
