A Typical Class

Class will begin with a 9-minute warm-up. Then the real fun begins as the class dives into max interval training. During this time, expect to perform body weight exercises that focus on cardiovascular fitness and strength through a series of intervals. Each interval series will consist of 4 exercises performed for 30 seconds each. Each series is then repeated 3 times with a 30 second recovery in between. With timed segments, you don't have to follow the beat of the music, you get in as many repetitions as is right for you! After you complete the intervals, class will finish with a stretching sequence to help cool-down the body.
