I signed up for the 24hr trial because I live across from crunch fitness Yerba Buena and I wanted to try out a free weightlifting class before committing to the gym, which I expressed to the staff. The manager, Jonathan Martinez, instead of letting me take the class made me do a "tour" of the (very small) gym (you can literally see the entire gym from the entrance so there's no need for the tour) while the class was going on, then sat me down alone in his office and **aggressively** tried to sell me the 6 month pass before i'd gotten the chance to step foot on a single treadmill. Really glad I didn't, because then I tried to go to the boxing class. Completely not stated on the website, there was a sub, who came up to me and told me that the class was not for beginners and it was sparring style. I didn't have my wraps because it did not say to bring wraps, but I was going to go upstairs to get them and he basically kicked me out of the class because I wasn't a regular. Long story short, this gym is hostile, and clearly they only care about their cut. I've been walking 15 minutes every single day to do yoga sculpt at corepower Fremont and have been very happy with my experience since! I would recommend this gym to not try to trap people into a subscription before they find out just how awful it is.
The so called GENERAL MANAGER ERIC , was extremely unprofessional & had an attitude refusing my FREE DAY PASS & trying to up charge me $10 to use the gym WHEN I CLEARLY HAD A FREE PASS , although I am a crunch member I’m not allowed into SIGNATURE CLUBS , & Being this was my first Time seeing a signature club, I signed up online to obtain a free pass so that I can tour the signature club and possibly upgrade my membership BUT ERIC’s IMMATURITY led me to be VERY UPSET & RUINED MY WHOLE CRUNCH SIGNATURE EXPERIENCE!! HE WAS CHILDISH & HAD SOME PERSONAL ISSUES WITH THE WAY I LOOK BECAUSE HE WAS VERY RUDE & IMMATURE & THOUGHT HE WAS ABOVE CRUNCH POLICY & REFUSED MY FREE GUEST PASS , PERSONALLY I THIBK HE SHOULD Not be allowed to work there because he is upsetting customers and hurting crunch as a business
visited for a single-day pass and had a great experience. The process was quick and convenient, and the facilities were clean and well-maintained. The gym wasn’t crowded, which made it easy to get a good workout without waiting for equipment. Overall, a smooth and enjoyable visit — perfect for anyone looking for a hassle-free workout option.
Great gym! Just wish they would clean they woukd not clean the sauna/steam on prime time Sunday morning 9-11am… can it be done another time like another super slow time…All else is great and staff is all cool too!
Love this gym! It’s clean, has all the necessary machines/equipments, a huge swimming pool, friendly staff and the best part - never gets too busy! Compared to other gyms in the neighborhood, Crunch Fitness YB is definitely the top one 💯!
