Get the most out of this super effective workout.
The most effective part of high-intensity interval training (HIIT) may actually be the very thing you’re getting wrong.
Too often, HIIT is seen as a “hardcore” sweat session where the more intervals you add, the better the workout becomes. And with some classes lasting an hour or more, it can be challenging to know the optimal amount of time to actually work it out.
But if you can go longer than 30 minutes, chances are you aren’t working hard enough.
