ABOUT FITNESS EXCHANGE
Founded in 1997, our company is a proud, locally owned and operated business. Our founder, Tom, had a deep passion for fitness equipment and noticed a gap in the local market. This realization led him to open his first shop in Conshohocken.
Fifteen years later, with his children grown, Tom immersed himself further into the business and expanded to the Lehigh Valley with a second storefront. He also ventured into commercial sales, providing a comprehensive, full-service experience to local gyms, schools, residential complexes, hotels, and more. This expansion established us as the go-to solution for fitness center needs. Over the past 25+ years, we have cherished becoming an integral part of the community in both Philadelphia and the Lehigh Valley.
