This is a video clip of my FAVORITE group fitness class called CozmoSize. I have never experienced something as tough or as fun as this! The instructor, Matt Cather, is a friend of my husband and I and we have participated in his workouts for about 4 years now. We love to train like athletes and that is exactly what this class is designed for. I encourage everyone to check out his work when you have a free minute! CozmoSize
