What is HIIT?

So what exactly is HIIT? HIIT, also known as High Intensity Interval Training, is a type of workout characterized by bursts of high energy exercise followed by short rest breaks. This type of training has shown to be incredibly effective at burning fat and building lean muscle.^1-4

We have harnessed this type of exercise in our Ascent and Apex programs to give you the best overall workout. Our full-body workouts are specifically designed to get you lean and sculpted. You’ll notice more mental clarity, better digestion, higher energy levels, and better overall body composition.^5-12
