Husband and wife duo, Jeremy and Diane Thomas, fold their 25 years of combined personal training experience into Fitness Partners Workout Center. Along with a cadre of trainers and instructors the team whips clients into peak physical shape, enlisting the help of specialized machinery and old-fashioned physiology. They sculpt cores with the aid of Pilates reformer machines and TRX suspension harnesses, and blast calories during indoor cycling sessions as students struggle up virtual hills or plunge sticks into the imaginary spokes of imaginary Lance Armstrongs. Mirrored classrooms help exercisers strike pitch-perfect poses or dance moves during yoga and Zumba classes. Although classes cap off at eight students, giving instructors ample face time with each guest, personal trainers kick the customization up one full notch with plans designed around specific goals, such as managing weight, building muscle, or living a healthier lifestyle.
