Equipment’s good; gets repaired fairly quickly. Love the skylight.But the STAFF. Whyyy are you in a customer service role // sitting at a front desk when you can’t be bothered to smile or say hello to patrons? Half these folks barely acknowledge your presence as you walk in — they can’t even be bothered to scan you in, so they just leave the scanner up and play on their phone.Honestly this sounds ridiculous, I get it. But I just can’t stand folks in customer facing roles who have zero customer experience skills.


Great gym with a friendly staff. I don’t use the cardio equip but the weights are good (except there are very few 5lb barbell weight lol). Friendly front desk staff. Bathrooms and showers a bit worn, but everything else relatively new


Good gym. Gets a little busy early in the morning.


Very clean! I absolutely enjoy working out at this location;)


You can’t cancel the membership here, and get hit with load of random fees. Looked for 30 mins on how to cancel it, and you have to submit a support request and wait for them to approve it before you can cancel (this is hidden super deep in the site). Friends have had the same issues.


After their recent renovation, it seems that the new staff are not as competent as their predesossors, nor as friendly. You might see them watching videos of their phones or just chilling on one of the couches set out for patrons. It's not as clean, and they often run out stuff like towels.


Been to four gyms in SF in the last year, this one's the has the most maintained/ functional equipment; weight stack rails are lubed, all pins and carabineers are intact. Looks like the staff has all changed and improved as well, they're more welcoming. Most importantly, this facility is CLEAN, they have an excellent cleaning team who I see wiping ever corner, step, bench, rail and behind and under all machines. Its something that I didn't know I cared about till I resigned up with this gym. My only suggestion with this place is they can improve on equipment placement, I like to look in the mirror to improve my form. Alternative solution, get more mirrors 😉


Quite honestly the best gym I've ever been to! I've never trained anywhere that challenges me so much physically but in such a supportive and friendly environment.


Horrible customer experience. Staff is rude, dishonest, and takes advantage of new customers. Would never recommend Crunch Fitness, worst gym in SF.


I booked a 120-min long gym session in ClassPass in this gym for 1pm. I was there at 1:25, and they didn't allow me to work out, because apparently I have to arrive not earlier than 15 mins after 1pm and no later than 1:15pm!I've been using classpass for different gyms for the past 3 months, and gyms never care when your booking starts - I've been coming 2 hours early or 2 hours late.Horrible experience, never coming back.
