This workout is challenging, but it's fun - and by fun we mean that by the time you're done, you're going to be satisfyingly exhausted and recharged at the same time, swimming in your own sweat. This is a calorie burning powerhouse, and it's sure to push your cardiovascular limits and endurance.

We've combined intervals of high intensity bodyweight cardio with kickboxing combinations. Switching back and forth from one training type to another forces you to keep your head in the game, and it helps to keep you from getting too bored. Though you'll be working hard throughout both training types, one kind of ends up serving as a rest period from the other.

This workout doesn't require a single piece of equipment, which means that it can be done anywhere, anytime. Remember to push yourself; you can make a big difference in caloric expenditure by making sure that you are staying present and challenging yourself to maintain a high level of effort output the entire time. On the flipside, you can always stop and take extra breaks if you need to. Just make sure that you don't let your body cool down too much, or your workout routine might get sidetracked.
