Forget everything you think you know about high-intensity workouts. Because INSANITY turns old-school interval training on its head.
If you've ever been to a Spin class, you know how that works. You motor along at a moderate pace for awhile â€“ then all at once, you kick up your speed and heart rate â€“ just for a minute or so. After that, it's back to a lower gear, giving you plenty of time to catch your breath.
But with INSANITY, you do exactly the opposite. You work flat out in 3 to 5-minute blocks, and take breaks only long enough to gulp some air and get right back to work. It's called Max Interval Training, because it keeps your body working at maximum capacity through your entire workout. You keep pushing your limits â€“ so your body has to adapt. That's how you get in such insane shape in just 60 days.
