Crunch Fitness

Giving U a 5 ⭐ because I wasn't pressured into buying the memberships (on my 3 day free trial) I actually felt like the staff was nice. They have mouthwash, Q tips, lotion in the bathrooms. Literally perfect for ppl that need that stuff, towels for the showers. Soap etc. I like it . My fav machine is the padded treadmill thankssss.

The gym is clean, very well set and complete. The service is amazing, specially Josh that really cares about people.

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.

Terrible customer service dude just seemed burdened by my inquiry into a membership. Absolutely short and impatience like I was keeping him off of his phone. He did even get up to speak to me. Told me anything to send me on my way. Definitely won't be joining this gym. Btw I didn't actually check the reviews before I went here. Now I totally understand the messly 3.7 rating. Don't join and save your money for something better.

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.
