IMP Fitness

A fitness center and an indoor turf field stretch across 17,000-square-foot IMP Fitness, a locally owned and operated establishment that's been providing fitness and wellness services to adults and youth for more than 10 years. Cardio, circuit, and weight-training equipment bustles beneath the glow of eight wide-screen TVs, and certified trainers conduct personal-training sessions and fitness classes. Throughout the year, lacrosse players can scamper across the 7,000-square-foot indoor turf, and participants in baseball camps and training sessions perfect their swings with the aid of pitching machines and target nets. The facility also offers amenities such as free WiFi, a smoothie bar, lockers, and scales that only read a person's moon weight.
