★ 5★ 4★ 3★ 2★ 1Been going to this gym since it opened under Crunch Fitness. It has since turned into a Curl Fitness and the improvements are amazing. There is plenty of equipment and free weights and it never gets too crowded. The staff are very helpful, especially the manager Gus, who recently went out of his way to correct a billing error promptly. Highly recommend.
August 12 · Will OrnelasI’ve been a member at Curl Fitness for a while, and I can honestly say this is one of the best gyms I’ve ever joined. The facility is always clean and the equipments are more superior than other gyms I’ve known.I felled down six seven times a year with a weak leg. Ever seen I met my trainer, Lily, I no longer fall again. She is fantastic and very knowledgeable on building your muscle and at the same time helps you to maintain a proper posture. After joining its training program, I have improved greatly in my physical health!!!Highly recommend this gym and its training program to you!!!
August 28 · Bob CheongI used to come to Curl Fitness as my friend’s guest, using the machines while she attended classes. After the gym was remodeled, I decided to sign up for my own membership. I really enjoy that I’ve been able to build a consistent exercise habit here. Now I attend all the morning classes—not just because I need the exercise, but also because the Zumba and Yoga instructors are far too wonderful to miss!
August 18 · Wendy WuI want to give a heartfelt thank you to Faith and Gustavo at Curl Fitness Diamond Bar, for their outstanding support and service. I had a lingering billing issue that originated with the previous gym, Crunch, during the transition to Curl. Crunch was supposed to handle it, but unfortunately, they never followed through.Since I travel frequently for work, my schedule is pretty limited. When I finally had the chance to reach out, Faith and Gustavo stepped in right away and resolved everything quickly and professionally. They were incredibly accommodating and made the whole process stress-free.It's rare to find such genuine customer care, and I truly appreciate their help. Thanks to them, I'm happy to be part of the Curl Fitness family once again.
June 24 · Bill HoldenI accidentally left my belongings (Air Pods, shoes, tracksuit, and gloves) locked in a locker overnight. When I returned to Curl the next day, all of my items were gone. They had cut my combination lock and emptied the locker without any warning or eviction notice. There were no signs warning members not to leave belongings in lockers overnight.I asked management where I could retrieve my items or whether they might be in the Lost and Found. The front desk staff member, Aneesa, told me they had no idea where my belongings were. She even suggested I check the dumpsters in the back alley. I felt humiliated and upset.How can a state-of-the-art gym like Curl Fitness Diamond Bar treat a member this way? I found their response rough and unsympathetic. I have requested to terminate my membership immediately. I no longer feel comfortable and have no desire to return.
