"Try this cardio circuit ladies! And guys" - Obi Obadike
Some of them I did more or less than 15 but you get the workout. This will kick your butt cardio wise.
Do this all in 60 seconds for one circuit. If you do 3 circuits of this you will increase your endurance, raise your heart rate, work your core, build your legs and work your shoulders and triceps/arms.
