About Us

Front desk and lobby at Steel Fitness Premier.

Steel Fitness Premier is a private, locally-owned fitness club located in Allentown, PA. Owner and Lehigh Valley native Tom Fenstermacher started his personal training business in 1995 out of the back of his car. He went on to build his business into a few fitness center locations that he either managed or owned. In 2006, Tom brought the Steel Fitness brand to the Lehigh Valley when he opened Steel Fitness Riverport on the South Side of Bethlehem, named to pay tribute to his late grandfather who was a machinist at Bethlehem Steel. In 2012, he opened Steel Fitness Premier, a much larger full-service fitness center in the west end of Allentown.

Today, Steel Fitness Premier is an exclusive fitness club, offering a facility and services found nowhere else in the Lehigh Valley. Our friendly staff at Steel Fitness Premier is dedicated to helping members in their wellness journey. We recognize that every member has different fitness goals and interests, and our highly skilled team will help you find the right exercises for you. Our people are another reason why our members love the experience at Steel Fitness Premier!
