609: 4x4: The Fitness Formula
This unique format will turn your classes into a 4-ring circus! The formula: 4 exercises + 4 minutes + 4 blocks = 4x4. Each round consists of 1 cardio, 1 lower body, 1 upper body, and 1 core exercise performed for 1 minute. After a short rest, repeat the block and move on to the next block of progressively more complex and dynamic exercises. This fast-paced workout will test your limits and keep your students coming back for more.
