This is my favourite Go-To workout from Jillian Michaels I do it pretty much every Monday as it is a great all rounder and really gets your heart pumping! You'll need an exercise mat and some hand weights for this workout.
The DVD is split into 4 different 20min workouts starting easy and getting harder. The idea is to do one workout for an entire week moving to the next for four weeks. Each workout is then divided into three circuits which you repeat twice. Jillian has broken each circuit into the 3-2-1 which includes 3 minutes of strength, 2 minutes of cardio and 1 minute of abs. This keeps the workout varied and interesting.
Personally I like to do two of the four workouts in a row - Workout 1 and Workout 4. This means I can get almost an hour of exercise in ranging from easy(ish) to really hard. I really enjoy this DVD and would definitely recommend you give it a go at only £8.08 from Amazon you'd be mad to give it a miss!
