Insanity is the HIIT workout that everyone is talking about! Why? Because INSANITY turns old-school interval training on its head. Rather than working at a moderate rate and then going to your max for a short period to get your heart rate up – with Insanity you do the exact 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 – so your body has to adapt. That’s how you get in such insane shape in just 60 days!
