This at-home cardio workout is only 15 minutes long and requires absolutely no equipment. The video is full of modifications and low-impact options too.
I decided to try this for a 5 AM workout, when I wanted to work but not get crazy sweaty. I am not an athlete but also not a beginner - I have been doing cycle and barre classes as well as a variety of online classes for quite a while. This got my heart rate up for sure, and my FitBit showed a third of the time in my cardio heart rate zone and the rest in my fat burning zone.
