And if you think about it mountain biking is all about intervals. In a short period of time, your body becomes a lean, mean, ass-kicking machine. Since Insanity doesn’t use any weights, your muscles won’t grow in size but they will improve in power.
Insanity uses only the resistance of your own body, so your cardiovascular ability improves quickly, your body fat percentage drops like a rock, and your muscles get sculpted. The benefits are very fast changes in your body composition. When you hit the lower-intensity periods, these muscles continue burning extra fuel (carbs and fat) even though you are at rest. Your heart rate should go above and beyond 80% of its maximum capacity, and your body is forced to use fast-twitch muscle fibers that aren’t usually hit with cardio or weightlifting exercises.
Insanity uses the opposite interval – 3 minutes of high-intensity followed by 30 seconds of rest.Įssentially your high intensity period (anaerobic exercise) is much longer than traditional interval training. With traditional interval training, your high-intensity exercise would last 30 seconds, followed by roughly 2-3 minutes of rest. A buddy turned me on to the INSANITY workout DVD's from Beachbody and I have to say I am blown away. So with old man winter (and my wife's good cooking and my love for food) adding some extra lbs this off season I figured I better get on track for the upcoming riding season.
