Best HIIT Workout App

High intensity workouts (HIIT workouts) are designed to help you burn fat over some time by only working out for short periods – 15 to 30 minutes on average. This makes HIIT very appealing especially to people who cannot find enough time to work out due to their busy schedules.

The only confusing part? There are quite a variety of ways for how you can do HIIT and if you don’t know where to start it can seem overwhelming. But fret not, there are plenty of apps out there that can help you get started! With so many options, though, deciding which is the right one for you is going to be the challenging part.

That’s where we come in! We’ve done the research on the best HIIT workout app and have gathered up 9 top options. So, let’s dive a little deeper into the world of HIIT so you can find the right app that will get you moving!

Are HIIT Workouts Good For Losing Fat?

HIIT workouts have a lot of solid benefits, but some still wonder if these exercises can help them lose body fat. I mean, if you only work out for a minimum of 15 minutes a day (in some cases, even 10 minutes), then how are you going to burn off fat in such a short period?

The good news is HIIT workouts is effective for burning fat because, while you perform these exercises in a relatively short period, you perform them in burst-and-rest. This interval of pushing your body to its maximum followed by a very short rest (then repeat) will force your body to burn off and utilize fat to keep up with the intensity of the activity.

The reason why HIIT is only done for a short period and why they are done in such an interval phase is to maximize your body’s capacity of pushing itself. Simply put, when you push yourself for too long and you push yourself to the max, you will not last that long and the fat-burning mechanism will take its time compared to if you worked out in such an interval phase.

The key to HIIT workouts is pushing yourself at the best that you can when you’re in that “intense phase.” But also be sure to take advantage of the “rest phase” so that you can give another boost when it’s time to push your body again to its maximum.

Now that we know how HIIT can help you burn fat, let’s jump to some of the best workout apps (some free with in-app purchases) that you can use for your workouts.
