The only thing you need for these three complete full body workout sessions is a pair of kettlebells and you're good to go. In the Day 1 workout you have 9 different exercises, including three paired supersets to make things fun. Total workout time is about 20-minutes. In the Day 2 workout session, you have 8 different exercises, three of which are supersets. This session is a bit longer at about 22-minutes. In the Day 3 workout you have 9 different exercises, including three paired supersets to make things fun. Total workout time is about 25-minutes. Interval based workouts like this one use shorter recovery periods between sets, compared to traditional strength workouts, and in turn this should help you burn more overall calories in the workout sessions.
