Laurie Weber
I workout regularly at KettleFlex as a class participant to really push myself harder that I would working out alone, AND the benefits of someone else to create a full-body plan as well as a coach to make sure my form is good. I also like to mix it up and strength train on my own. The other clients are considerate and friendly.

Went for the first time today and focus on form, explanations behind technique and programming are great.
It’s great to have some form reminders and options as there are different styles/approaches to kettle bells and lifting in general.
Friendly atmosphere and people.

Great gym, great people! Never the same workout, always welcoming trainers and a good mix of equipment including TRX. Large well-ventilated/open indoor space and plenty of shaded outdoor area. I love what this gym and the amazing trainers here have done for my fitness level and my joint health

We're not a big gym.
We're your gym.
Kettle Flex Fitness was built on one idea — that everyone deserves a coach who actually knows their name. No crowded classes. No cookie-cutter programs. Just certified trainers, small groups, and a training system that's been producing results in San Diego for over a decade.
