At Challenge Fitness we require high quality durable equipment that is able to sustain heavy use during our small group classes and personal training sessions. For that, we turn to j/fit to meet our needs. We have used j/fit’s kettlebells, dumbbells, medicine balls, foam rollers, ropes and other functional training equipment for many years now and have always been pleased with the quality, affordable price, and of course their service is hands down the best! We are proud to have j/fit as our partner in helping our clients reach their fitness goals. Thank you, j/fit! — Mike and Patti Case, Owners, Challenge Fitness, Vancouver, WA
