I was reasonably fit when I started training with Joe, but in more narrow ways (largely from cycling).

I have a stellar experience each time I visit Fitness SF. The front desk guy, Ryan, is usually…read moreworking and has been very friendly and accommodating. He's also a dog lover and took great care of my dog while I worked out. Even gave him some treats which was super sweet of him!! I was initially worried I might not have access to the same equipment I had at other locations due to the smaller space but that wasn't an issue at all!! They also have a bunch of stuff to aid in recovery that I didn't know about. Ryan recommended the inflatable compression sleeves for my legs. I had never tried them before and he walked me through putting them on. Highly recommend this gym and am grateful for Ryan!

It honestly feels like you're in a submarine. The men's locker room is tiny, and like most gyms,…read morethey've oversold memberships and it shows everywhere. The pool is pure chaos. About a year ago, they had a policy of onsite lane reservations, which is the right thing to do if you don't have online lane reservations. You had a clear start and end time, could plan your workout, and actually get a full swim in. For some reason, they've stopped doing that. Now you show up with no idea if you'll even get a lane, let alone finish in time to get to work. They're also allowing three or more people per lane, which is just unrealistic. Once a third person joins, it stops being a workout and turns into traffic management. You can forget about flip turns entirely. The lane speed designations don't help either. Most people are on tight schedules and aren't going to wait around for the "right" lane to open up. They also block off a lane for personal training, which is understandable, but that lane could still accommodate another swimmer. Decisions like this chip away at what's supposed to be a core service. Most pools in the city allow reservations. You can reserve a lane. Some even have a no show fee which totally works. you can't trust humans to so the right thing here because they in most cases won't. Bottom line, the lack of reservations and overcrowding make it impossible to plan a consistent, efficient swim. It turns something that should be straightforward into a daily gamble.

No frills, no nonsense gym that has everything you need to get a good workout in…read more After moving back to San Francisco in the middle of last year I was looking for a gym that was more local/ in my neighborhood that I could walk to rather than taking public transit to another part of the city. That's when I came across the Sunset Gym this past December. I started my membership with a week long pass and eventually converted it to a monthly membership. (The payment for the week pass went into my first month of membership) Pricing wise this place is a very reasonable compared to the bigger chains (i.e Fitness SF), but admittedly you are also restricted to one location. For me though, that's not a problem as I wanted a neighborhood gym more than anything. The gym itself is great - it's old school (think OG Gold's Gym style). Downstairs has plenty of free weights and a good selection of machines. Upstairs has a dedicated Cardio area, a spot for stretching, as well as additional free-weights and an outdoor area. Staff I've interacted with so far have been wonderful. Very glad to have found a great gym close by to where I live

There is nothing like a local neighborhood gym, where everybody knows your name (just kidding, but…read moreyou all start to recognize each other if you are a morning, midday or evening gym-goer for sure), with friendly staff and equipment that may not be the latest and greatest, but it's familiar, it works, people take care of the machines and weights and wipe them down with the many spray bottles and paper towel stations, and there seems to be one of everything you could ever want. Definitely a transit-first or walk-from-your-home-type gym, 9th and Irving is not known for its parking (though it IS known for it's ever-present MTA carts zipping around). Love the towels, the multiple bathrooms and showers, the fans everywhere, and the small outdoor area on the second floor.

This is the best gym I've attended in my 22 years in SF. I was a member of the 24 Hour Fitness that…read moreoperated in this space pre-pandemic, but Live Fit spruced it up with much better equipment and made smarter use of floor space for a less crowded feel. Speaking of crowds, there usually aren't any. I rarely wait long for even the most popular pieces of equipment. I love that Live Fit is open on major holidays (they just go into an unattended/automated mode where you let yourself in via a QR code in the membership app), and they don't allow third-party trainers, who in my experience are some of the worst equipment hogs. Super friendly staff, too!

As a long time SF resident, with some experience with personal training and fitness i can recommend…read moreKate with no hesitation as a personal training. She is knowledgeable and makes the hard training fun somehow. I leave the sessions feeling strong. I don't take for granted when someone is professional like Kate. I've encountered young trainers that had to do some growing. That is not the case with Kate. She is responsible, communicative, fun as a bonus and her heart is in the right place. She cares and makes the experience worth the effort. The Castro branch is clean, and Casandra is always ready to help with a smile. Thank you good people who do good things in this world.

The stairmasters have been broken for some time now with the first one being broken for 2-3 months. One by one they broke & now they're all broken. I understand gym equipment can break from time to time but the fact that ALL stairmasters are broken, 30% of ellipticals are broken, a handful of treadmills, & the weight machines upstairs are missing pins, broken cables, etc is just pitiful from a gym like this. VARIOUS THINGS HAVE BEEN BROKEN FOR MONTHSSSS!!! The LEAST they could do is communicate to us what is going on & what they are doing to rectify this situation. I usually do not write reviews unless necessary to make a change to the establishment. I hope this review finds its way to someone who can do something Side note: this gym also is starting to have an issue with people hogging machines while doomscrolling on their phones between sets as they are "resting". If that grind your gears, this is a heads up. Side side note: notice how management only replies to "positive reviews"; this is a critical review from an intermediate gym goer(3 years of hypertrophy training) for some context.
