I have attended a handful of Duality’s RESCON classes and they are addicting!! They are my new favorite workouts, filled with great variety and enjoyment. I love the way I feel after. I’ve had 3 different instructors and loved each one, they do a great job of making sure your form is correct and motivating you to push your limits. Took my husband along and he loved it too. Duality offers the BEST workouts!!
