24 Hour Fitness

Gym needs to fix treadmills faster when they break, but other than that: great facility and staff for the price charged.

super crowded at 6pm. the gym rats here aren't the most considerate (vs crunch). the staff is great though!

The gym is big, 2 floors. Brian one of the personal trainers is the best and is flexible! He knows a lot about chronic pain and will work with you.

Definitely smells like a gym . Very spacious . Love coming here at off hours. Convenient parking on the street at off hours.

Saturday 9am Zumba Class with Cris is the best! Amazing choreos! Great energy!

best value gym for sure in SF. go after 9pm ????

Group classes in the early evening are a good way to avoid the crowds.

Jeff is my favorite spin instructor . He has the BEST playlists and they're different every class !

Don't be surprised to see someone work out in jeans or eat chips between sets.

There is this creep old asian man that watches you.. If he talks to you report him to the staff for harassment.

Try out the hip hop class with Gino at 8:30 pm on Tuesdays!

Theft problem in the locker room here. Multiple people had their lockers broken into. I had my wallet and phone stolen here.

Just got refreshed with new paint, new pads on the equipment, TVs upstairs, and remodeled space on the second floor.

Adrian's BodyPump and BodyAttack are killers!!!

pj is the best turbo kick instructor ! he really gets the class hyped up!

Nice spacious gym facility

wish the treadmills were not so close to the walls so one can watch the TVs above

The protein pump smoothy with an extra whey scoop is great to keep some calories in you throughout a lift.

12pm wed. Cycling class ... Fun and a great enthusiastic instructor

The stairs in the entrance is enough of a workout.

Try muscle mass at the drink bar by the register ... So good after gym time

Bring your own towel and don't pay the monthly rate for towel service. Very often they don't have clean towels so you will be stuck drip drying.

Think they are running a towel scam. You pay for monthly towel service and they never have clean towels but let you know you can purchase one from them. Sounds fishy to me!

Wear flip flops for the shower . The locker room is a slippery mess at times.

Turbo kick , strength training , 24 Hour Lift and Body Pump are great workout classes . Will try Zumba and hip hop one day.

Nobody in this GYM re- racks their OWN WEIGHTS THEY DON'T KNOW WHAT GYM ETIQUETTE IS Dumb Asses!

SF Weekly's Best Of 2011 - Reader's Poll - BEST FITNESS GYM

Saturday fun and that is Cris' 9am Zumba class ! :)

Joel, is great! The perfect balance of hard ass and nice guy.

Sometimes it really smells like fart up in here. So it best to avoid super hot days...

After your workout try the Mocha Java Jolt with peanut butter . It's low in calories, high protein and delish.

For turbo kick class ... Take it with matt he's the Best !

Got to get here at least half an hour earlier if you want to get into the spin class . Even then it might already be full...

Try some tkb. Lot's of machines here! workout hard so you can get your grub on. <aclass="entity url"rel="nofollow" href="http://www.grubcrawl.com"target="_blank" data-sig="LkcssiRpfv78XM1pw0G0DTRJu00=" onmousedown="fourSq.ui.OutgoingLink.mousedown($(this), event)" data-source="tip-text">www.grubcrawl.com</a>

24Cycle with me, Monday and Thursday at 630P!!! New music every week.

Lighter traffic from 9a-1130a and 1p-330p and after 8p

Saturday evening workout. No one in the studio room.

I like body pump ????????

The Berrylicious smoothie is DELICIOUS.

Tonight, we will conquer that rep! Hoo-rah!

On Wednesdays its happy hour 4-8 at Nrgize, the smoothie bar in the gym ! $1 off all smoothies ! Yumm

Don't do bicep curls with the bench press bar .

If your treadmill won't work, check the stop button. They stick!

Believe...

peeping toms on the prowl here. -_- cover up ;p

Any workouts needs to be started with cycling ;-p

Every time I'm in the men's locker room I'm tempted to knock out the short , disgusting, naked old men drying off thief sacks.. Use a god damned towel.

<3 the running machines in the right

Amazing Protien Shakes

They're open 24 hours
