Some locations offer a kids club for just $10 a month, which is amazing for parents. I don't regret my move at all -- I only wish I had done it sooner. Staff here isn't as friendly as whipple I would say , the front desk hardly even says hello but besides that the gym is great. I have had no issues, just wish they'd bring kids club here. UPDATE- since my review honestly the staffs done a 360 as far as the front, theirs always a guy at the front when I come in, he's super attentive and greets everyone. I've visited both the Whipple and Fremont locations, and both are great. The only thing I wish is that the Fremont location would have a kids club and I'd make this my overall home gym.

Avoid this location. If I can give it a negative star that's what it would've received. Poor…read moremanagement and personal training staffs Most personal trainers are rude and possessive of the turf area especially the trainer Asia and will constantly kick you out of the area or abruptly grab your equipment stating that it belongs to the trainers only. The trainer Asia was confrontational and disrespectful in the turf area. Managers John and Gabriel just watched and didn't attempt to diffuse the situation. Wouldn't recommend this place.

It's one of my preferred spots in the East Bay for the layout alone. However, the cleanliness is a major drawback. The carpets have clearly seen heavy foot traffic and are holding onto a noticeable odor--a good shampooing is overdue. More importantly, the mats are dirty; I found significant grit and grime on today before stretching(see photo). I always wipe down equipment before and after, but the level of buildup here is tough to ignore. With some better maintenance and floor care, this would easily be a 5-star gym.

I've been coming to City Sports in Hayward (off Hesperian) for about 4 years, and I'll admit--I…read moreused to agree with the one-star reviews. Machines would stay broken forever, things weren't always the cleanest, and the vibe was just "meh." But recently, things have changed a lot. Ever since Anant took over as manager, the gym feels like a whole new place. Machines are getting fixed right away, the floors and equipment look cleaner, and there's even a new Pilates setup with classes. The protein shake/snack bar is open now too, which is a nice touch. One thing that really showed the difference: when that TikTok trend went viral and people started stealing the weight machine pins, the old City Sports probably would've just let it drag on. Instead, the staff got creative, found workarounds, and had replacements quickly. Problems aren't ignored anymore--they're solved. Overall, I'm really impressed with the turnaround. Credit to Anant for raising the standard. The gym feels cared for again, and it's honestly the best it's been in years.

The Swimming Pool: It's the perfect temperature and not overly crowded. Also, people in the pool are very respectful. And the water is extremely well-maintained.

Highly recommend this place.

I would like to express my dissatisfaction with my experience at 24 Hour Fitness. During my visits,…read moreI observed what appeared to be inconsistent treatment of certain members by management, which contributed to an environment that felt less welcoming and inclusive than expected. Additionally, the facility did not appear to be maintained to an acceptable standard. The gym was frequently dusty, and equipment, including dumbbells, was often left unattended throughout workout areas. This lack of organization created a cluttered appearance and raised potential safety concerns. Overall, cleanliness and facility upkeep did not seem to receive adequate attention.  I expect a fitness center to provide a clean, safe, and professional environment for all patrons. Unfortunately, the condition of the facility, combined with concerns regarding member treatment, fell short of those expectations. I encourage corporate management to review these concerns and take appropriate steps to improve both facility maintenance and the overall member experience.
