What is Insanity?
Insanity is a total body workout that requires no gym or equipment.
Insanity works in the opposite way to a spin class. Instead of motoring along at a moderate pace for awhile – then all at
once, you kick up your speed and heart rate – just for a minute or so. After that, it's back to a lower gear, giving you plenty of time to catch your breath. Insanity uses max interval training that makes you work flat out in 3 to 5-minute blocks, and take breaks only long enough to in air and get right back to work.
