Within an intimate studio characterized by exposed-brick, Tiffany-box-blue, and burnt-orange walls, Allegro Coaching stirs with a bustling schedule of more than 20 different group fitness classes per week. During warm months, coaches lead outdoor boot camp classes at parks around Grand Rapids. Certified instructors, many of whom hold degrees in exercise science and have trained MMA fighters, shepherd both exercise-uninitiated and seasoned athletes through the cardio and strength-training exercises of boot-camp sessions or muscle- and definition-building TRX-suspension-training, Pilates, or boxing classes. The studio's personal trainers also travel to local businesses, where they enlighten employees with wellness counseling and onsite coaching and offer practical tips for staying active in the office that move beyond typical exercises such as crab-walking in circles around cubicles or shadow-boxing the water cooler.
