Insanity is a total body workout that requires no gym or equipment; however, you will love taking this class at Pursue Fitness. Use the power of the fitness class to motivate you using your own body weight for resistance. The program is based on a fitness method called “max interval training.” In traditional interval training, you exercise at a very intense pace for a short period of time, and then rest for longer periods in between. The idea is to increase your aerobic fitness level while burning fat.

Max interval training has you work as hard as you can for 3-minute intervals, with 30-second periods of rest in between. Exercising at this extreme intensity can allow you to burn 1,000 calories in a single hour!  Try Insanity today at Pursue Fitness in Springfield.  Insanity is free to all gym members with a Plus membership.
