This video isn't afraid to jump straight in. No minutes of talking, no fancy intros, not even a specifically planned warmup. It requires you to be stretched and ready to

work your butt off from the moment you start it. 

15-minutes of going up and down in reps, doing a dumber of different highly intensive exercises, all of which benefit

different parts of your body, easily turn this video into a regular favorite. 

Coming in at less than 10 minutes, this video is definitely on the shorter side, but it's totally meant to be that way. Whether you decide to use this workout

as a more intensive workout or repeat it for multiple sets, it is super beneficial. 

The featured exercises include things like plank jacks, split lunge jumps, and burpees, and while all

of them are pilates inspired, they are no less intense. 

Yoga and HIIT are sometimes thought of as two ends to a very long spectrum when it comes to exercise, but this workout manages to blend them perfectly and effectively. 

Classic

yoga moves are transformed into intense exercises that workout everything from the legs, to the arms, to that core. 

Everyone needs at least one workout that specifically targets fat burning on their roster. And this HIIT bodyweight workout does just that in only around 10 minutes. 

Hardcore "walking planks with

a jackknife twist" are combined with things like mountain climbers and pushups to ensure that you and your body get the most out of your HIIT experience. 

Created specifically for those living and working in tight spaces, this workout can be done sans equipment and in even the tightest rooms in your house. About 10 minutes of HIIT cardio

makes this workout ideal for those days when you're looking for something a little lighter but still effective. 

This video has everything you need! A great cardio warmup, an interactive screen, active recovery times, and one of the best HIIT body toning workouts you will ever complete. 

The knee

highs and mountain climbers included in this workout may be old school but they get some exciting new spins too!

Plyo, also known as jump training, is an amazing technique used for increasing power and strength while also giving your muscles one crazy workout. 

While the trainer in this video does

use a jumprope for a small portion of the workout, she gives clear and concise alternatives for those that don't have access to one, making this video just as helpful

as it is intensive. 

Cardio is more than just running on that old treadmill until your legs fall off. Using repetitions and circuits, this HIIT workout isn't timed but that doesn't mean it isn't still

badass. 

Exercises like star jumps, fly jacks, and rear lunges are utilized to help burn fat in as little as 15 minutes a day. 

The word "bootcamp" definitely doesn't tend to signify anything easy, and this video is no different. 

Super intense spider jumps and supine legs are done at high reps and while a

couple of the moves in this video use dumb bells at certain points, cutting them out won't affect the outcome much. 

You don't need to do this workout on the roof of your building for it to be effective, but we're sure it doesn't hurt! 

This is 15 Minutes of exercises targeting the

core, the legs, and the lower back. This routine will seriously increase that heart rate and get you working up a great sweat!
