You won't find pools and racket-sport facilities at Spunk Fitness. You also won't find overly aggressive sales reps. What you will find are low membership rates, convenient month-to-month memberships, and something practically unheard of in other gyms—free unlimited fitness instruction. Instructors are always available to ensure Spunk's members are getting the most out of their workouts, which might mean showing them how to use the cable trainer or perform a proper squat without extending their knees over their toes.
