If you have a couple of dumbbells handy and are ready to apply an extrinsic load to the body then get ready for a workout that will leave you feeling Jacked for the day and a little sore the day after. This is a full body workout and to get the most out of it you'll need to get your breathing right and establish a rhythm that works for you. That actually will make a huge difference to how much you burn in this particular workout as well as how you feel afterwards.
Extra Credit: Use 6kg (~12lb) dumbbells minimum
