Polarize Crossfit has changed my life. When I started 2 years ago I was overweight and had Non alcoholic fatty liver disease. In just my first year my liver returned to normal and I lost 60lbs. Thanks to the amazing Coaches and athletes!

I have been at Polarize CrossFit for over 7 years now and am so grateful to be a part of this family. I have gotten faster and stronger during my time here and can truly say I am in the best shape of my life. Coach Jo’s knowledge, experience and encouragement has been so amazing and I feel like I am constantly learning new things to support continued growth and increase my skill level. I am excited to continue challenging myself and working towards new goals. Thanks Coach Jo!

I’ve been coming to Polarize for 5 years and can’t imagine working out anywhere else. I started in the Sweat Bootcamp because I was convinced CrossFit wasn’t “for me.” After two years, Coach Jo finally talked me into trying a CrossFit class—and I was instantly hooked! I quickly realized I could push myself way more than I thought possible, and I’ve seen real gains in both strength and confidence. The coaches and the Polarize community are what truly set this gym apart—supportive, motivating, and welcoming at every level.

Been there for years, my dad coaches and I've always loved it, I love lifting and adding in such great cardio to that is amazing

Best CrossFit gym in Oceanside (and San Diego). I went consistently to this gym for over a year, and had an entire body and strength transformation. Workouts are hard but efficient. Coach Jo works with athletes to help customize/scale workouts, but still ensures they have the same anaerobic effect💪🏼 Polarize is the best of both worlds: 1) if you’re new to CrossFit (like I was) this is a perfect start or 2) if you’re already a CrossFit junkie, you’ll feel right at home. I couldn’t recommend this gym more! Try out the 5:30am workout crew🔥🔥🔥

Polarize is a great gym for all levels of fitness! Whether you like CrossFit, barbell, or are just starting on a fitness journey, there are classes available to meet your needs! We’ve been going to polarize for quite a few years and can’t say enough about the people (especially Jo) involved. Great setup, great people, great workouts!

Been going for about 3 months now, this gym is great! Welcoming members, great staff, Coach Jo is awesome! No judgement, all workouts can be modified to work for you no matter your fitness level, modifications are laid out for everyone so you won’t feel singled out. 10/10

Best Gym in Oceanside! Been here a little over a year and I have learned so much about proper techniques and actual knowledge of how to better myself as an athlete. If you want a place where the people (and staff) care about your health and your personal growth, then this is the spot. As an athlete, if you want to choose your new gym home, then you know that when you get here Coach Jo has your back! Be prepared to sweat your butt off. This is the spot to make your goal a reality. 🫶

Love Polarize CrossFit! The coaches always make sure we are safe with the movements. Everyone is nice and amicable, it feels like a big family.
