Crunch Fitness on Union Street is a solid gym with a lot to offer, especially if you're looking for a vibrant, no-frills workout spot in the heart of SF.
The equipment is well-maintained and there's a good variety—plenty of free weights, machines, and cardio options. It can get a bit crowded during peak hours, but that’s expected in a city gym. If you time it right (early mornings or midday), it’s much more manageable.
Staff is friendly and helpful, and the vibe is energetic without being overwhelming. There’s a nice mix of people here—everyone from serious lifters to casual gym-goers—so it doesn’t feel intimidating.
The classes are a highlight. From HIIT to yoga, the instructors bring good energy, and the schedule offers decent variety. If you're into group fitness, it's definitely worth checking out.

Rude front desk. Never experienced such experience in all 4 states I’ve lived in all cross the United States from any major brand gyms. Even Crunch’s own employees in other states and other locations don’t behave like this. Shocked.

Avoid. I suffered an injury and no longer could use the gym facility. They made it impossible to cancel my membership, at times telling me I need to cancel in person. I was hospitalized and bed written for several months, canceling in person was not an option. They are now pursuing collections against me for $290.
Jonathon Martinez is a terrible manager. He’s had the opportunity to do the right thing multiple times but refused to acknowledge my calls and emails.
Terrible business practices.

Friendly and helpful staff. I forgot my wallet after asking to buy a drink. The staff member suggested they could pay for it and I could just Venmo them. I went ahead and passed on the drink but the willingness to solve my problem was not overseen.

This is an ok gym, typically extremely crowded right after work.
Generally, the front desk service can be hit or miss. Some staff can be friendly, but I've been actively ignored by multiple staff who will chat together even while seeing that there are people waiting to speak to them.
Recently, I tried to inform them of a broken machine that people were trying to use which was unsafe and they were slow to address the issue.

Nice facility and machines but.. Overcrowded and yet the sales reps are extremely aggressive to sell more memberships especially if you go in to try it out or to take a single class. At what point does the gym simply get too crowded to use! I think we’ve passed that point.

I like Crunch, but the yoga class with Chris S has a really negative energy. He comes across as mocking and condescending, and he seems upset about something, which doesn’t align with the spirit of yoga. I’ve taken his class three times because the 6:30 PM time works for me, but his attitude makes it hard to enjoy. My friend also stopped going to the class due to his constant mocking and rude comments. I’ll need to find another class at the same time since the negativity is too much.

They advertise 1 or 3-day pass to try the gym but they wouldn’t honor it because I didn’t have a CA-issued id with me. Asked for a lease to prove that I indeed live in the city.
It might be their policy to only allow locals to get a trial pass but it’s not smart and they just lost a potential customer.

Just went in to inquire about a tour.
Was rudely pressured by Robin to give I'd and sign a waiver and then refused to give me a tour of the facility, forced to have a staff member contact me after garnering my personal information to tell me basic rates.
The arrogance, for no apparent reason, the hostility at my interest in seeing the space along with hers and Earnestos unbelievable show of disrespect have shown em exactly why neither I nor anyone I would ever send there would want to use this gym.
What worries me is how they got my personal information in their system. What these haters will do to abuse it.
They had better delete that information IMMEDIATELY.
It's traumatizing to have such hateful people represent a gym.
How do these snobs live with theirselves.

Been coming to this gym for 3 years now and I love it. The staff is incredible and kind, the other patrons are friendly and the gym is spotless. In a city with few all purpose gyms - crunch is the best for its location and price. Love the union st staff the most

Small but has most things you need! Pretty similar to the YMCA or neighborhood small gym. Treadmills are really out of date. Also there is no AC so for hot days it’s unusable, even the fans aren’t great for when the heat rises to most of the equipment on the 2nd floor.
