Fitness & Gyms in Castro Valley, CA

“Love this place. If your looking for a place to really work out, then this is your place. All the trainers are genuinely helpful to your specific goals. I was so much more comfortable working out here than at a big chain gym. The best part about the group classes is that they allow you to workout the right way & at your capability so you do not hurt yourself. Each class offered is intense but with slightly different instructor technique - will keep you coming back for more (and sore)! Lol Attended this gym for 6 months, unfortunately, due to work schedule and travel, could not continue. I do want to give special shoutout to the owner Marlon. He runs the business with high ethical and moral standards, always keeping customer goal as priority. Thank you Marlon for great experience with Body Mechanics.”

“I've been going to D's since 2016 and feel like it's home. My favorite classes are Ivania's Tues morning strength class and Jess' Thursday evening zumba class. They're incredible instructors and make all who come feel welcome. The gym has everything you need: free weights, machines, mats etc. I can't wait to see it once renovations are complete! The new owner has taken time to consider what an ideal women's gym should have. Once, it's all finished it will look and be THE place to workout in Castro Valley. Don't hesitate to check D's out!”

“Best fitness membership of my life. The entire OTF team is super positive, supportive & so much fun to be around. It's changed my life. I never would have imagined that I would find a fitness program that I would look forward to, but this is it!”

“Been coming to the Castro Valley gym for 2 decades as it's my home gym. Don't underestimate it's small size... it packs a punch and it has all you'll need to reach your goals. It has for me. The staff is incredible and are always welcoming and helpful. Eric in particular stands out and is an asset to 24 Hour. He's always encouraging and is looking out for the best experience for anyone who walk in the doors. Lately, an influx of younger members of highschool age, which include my daughter and son via the buddy pass option is a great way to pass on the gift of health and fitness. Seeing that this next generation valuing this is priceless and the Castro Valley gym is part of that success!”
