Back for another round of Fitness Blender's signature 1000 Calorie Workout challenges!

Here we aim to give you everything you need for a highly effective workout in a format that uses so many different training types that even though the workout is long, it's impossible to get bored. After a quick cardio warm up, we move into a HIIT routine, followed by a thorough abs, obliques and lower back workout, next onto a total body strength workout, finishing up with a cool down and stretch.

No muscle group is left unworked and all you need is a set of dumbbells - even if you don't have a set of dumbbells, this is still plenty of a challenge with just bodyweight.

We did something in this 1000 calorie workout that we've never done before. We did the routine together so that one of us could show the advanced version of each exercise, while the other moves through the routine doing a low impact version of everything that is more accommodating for the immediate level exerciser or for those who need less jarring impact on the joints. Choose your level of difficulty, and move back and forth between the two levels if you need to in order to make it appropriately challenging for you specifically.

Remember to push yourself, but to listen to your body and feel free to stop and take extra breaks if and when you really need them. Sometimes even stopping for a few seconds can give you the extra energy you need to push through the end of an active interval. If your form ever starts to suffer, take a quick break before jumping back in; all throughout the routine but especially during the strength training, good form is important.

Does this workout really burn 1000 calories?
Some people will burn more than 1000 calories, and some will burn less. As you can see in the video, there is a wide range given for the estimated calorie burn. Expenditure is dependent on a number of variables; here's how we come up with our calorie burn estimates. We advise not obsessing about exactly how much you've burned during any given session; the exact numbers are far less important than the fact that you're exercising and making yourself fitter, stronger, and healthier.
