What Our Members Have To Say

They go above and beyond

WOW. I liked the gym when I signed up, but this company has gone above and beyond during this COVID-19 process which really set the bar high for other gyms. I also just received a personal phone call from a gym employee checking in on my well-being, asking if I need anything, and updating me on the gym opening. I really really cannot say I have been a part of a better gym. I am extremely satisfied and they are a true gem to this Marysville/Yuba City area. Thanks Training Zone!

I found the best gym near me!


Literally the best place on earth next to home. Workers always great very nicely and tell to to have a great day. It’s the little things that make this place better than anywhere else. Never had a bad experience here an I’ve been coming for about a year! Keep it up. Even though your already the best!

Great Experience! Very clean and tidy.

The staff was really friendly... I was also pleasantly surprised how clean the gym was. Lots of members using the disinfectant wipes strategically placed around the gym. The staff was tiding up and re-racking weights almost hourly. Training Zone was tidy and organized. The bathrooms were really clean too.

Whenever I'm back in town I'm definitely going back to The Training Zone. Hands down the best all-around gym in Grass Valley.

A gym fit for the whole family!


Training zone is such a family oriented gym. Everyone on staff is so friendly and encouraging. After starting classes and getting to know people, you miss one day and everyone's asking what happened. The combat class is one of my favorites, you burn a ton of calories and it's fun. The majority of their classes are included in your membership too. Love my gym!

The best gym with the best classes!


I have been to a lot of gyms and by far this is the best gym, so friendly and they make you feel like family wanting to work with you to be your best, the best trainers the best classes and the best strength and conditioning/ Spartan classes ever. They help build your self-esteem. I can't say enough about the employees except thank you, thank you.
