Dear Craig and Yvonne (Owners) Thank you so much for your…read moreincredible hospitality during the 2026 Semifinals. From the moment I walked in, your members made me feel like family, and I was so impressed by the depth of knowledge your coaching team shared-I'm walking away with some invaluable tips! You've built more than just a gym at Diablo CrossFit; you've created a truly inspiring environment. Your passion for fitness is contagious, but what moved me most was seeing your dedication to one another. Four decades of marriage is the ultimate 'strong finish' and a beautiful example to us all - which is just as important in today's world. Thank you all again for a truly great experience. You are a blessing to the community and #fitnessandcouplegoals

Steph is truly on another level. I'll be honest--I'm not the easiest client. My body doesn't always…read morewant to move, bend, or flow the way it should, and that can be frustrating. But Steph never once makes me feel limited or difficult. She meets me exactly where I'm at with patience, precision, and a genuine commitment to helping me improve. What makes her stand out is how much she wants you to succeed. You can feel it in everything she does--every cue, every correction, every push. She doesn't just coach from the sidelines; she's fully invested in you, finding the right approach to get your body into the correct position safely and effectively. No matter how many adjustments it takes, she stays locked in until it clicks--and somehow, she makes you believe in yourself in the process. Her knowledge is next level, but it's her energy, encouragement, and ability to truly connect that makes the biggest impact. She knows how to get the absolute most out of every single session, while still making you feel supported, seen, and motivated. It honestly feels amazing to have a coach who genuinely wants you to be good, to grow, and to win. That kind of care and dedication is rare--and it shows in the results. If you're looking for a CrossFit coach who is skilled, patient, motivating, and all-in on your success--Steph is it. Absolute 5 stars.

A decade ago, I was very much into Crossfit, but after a decade going by and the gym I went to…read moreclosing, I didn't think I would ever have the motivation I use to, to get back to it. But 510 changed that for me. The first day I walked in there I immediately knew this was where I was meant to get my health back. The community here is full of people you won't necessarily find just anywhere. It doesn't matter how fit you are or how fit the person next to you is, because we will be cheering you on, supporting you in a way you didn't think people did anymore. The coaches keep things fun, but also make sure you are being safe. They are hilarious and also extremely motivating. I really haven't found a gym like this since my old one closed, and to be honest, 510 is even better! I have injuries from a car accident years ago and the coaches are always ready to modify a workout for me. They are extremely knowledgeable at what they do. It doesn't matter what level you are at or if you are injured, I promise you that you won't regret stepping in those doors. It truly changed my life (physically, mentally and emotionally). Every time I go, it helps me believe in myself a little more and some of the best people I have met in my life, I met through Crossfit. Don't hesitate. Run here. You won't regret it.

I'm usually shy and stayed to myself, but was welcome by the coaches and people there. It's been an amazing journey! Rob and Alex supported my health goals, pushing me to get my PRs. I was so happy when I was finally able to do a bar muscle up! All the people I worked out with are super supportive and fun! We push each other and hold each other accountable. And I have made good life time friends at this gym. I am forever grateful for this company and the community.

These past two years have been pandemically bad. Being home all the time can lead to bad habits and terrible mental health. So I joined this gym. I'm no where near the level of the veterans at this gym, but I keep going and keep surprising myself every time. It's tough. It's fun. It's structured. Its clean. Its perfectly located. it took a couple months before it became part of my new life style, but once it did it's powerful mental and physical medicine. Coach is a character. He reminds me of strict high school teachers, hard exteriors but all love in the inside. Unless you forget to sign in, then he is just mad... lol. This gym is for you If you tried regular gyms and don't know what you are doing, or need more out of your workouts. This place is definitely for you if you need a group fitness vibe, I call it collective struggle. Partner workouts are my personal favorites. I don't know what I'm doing but I know that the people at this gym are going to help me figure it out. One last thing! This gym has no mirrors, and I love that!

I ended up having the best fitness experience of my life. Coach David was great and taught me how to do all the barbell movements and gave the right amount of encouragement and coaching to keep me coming in. From October 2021 to May 2022, I went to the 5am classes here, which were perfect for me to get my workout in before workout. I made amazing friends with all the gym members. My wife and I have to move now because of work, but this gym had a huge impact on my physical and mental toughness. I'm looking forward to continuing CrossFit in the city we're moving to. Today was my last day at Matador, and the crew sent me off with an amazing farewell and goodbye card! I can't think of a better, more hard-working group of folks. Not just gym-mates but friends.

I've been coming here since 2023 and have nothing but good things to say. You will be welcomed by the coaches, the class, and get a great workout in. There are many class times starting from 5am to 6:30pm and each class is an hour. Some might say that the monthly cost is pricey compared to regular gyms but it's totally worth it. They also have punch cards if you don't plan on going many times a week or even drop in for $25. I would 10/10 recommend this gym- you'll get a great workout in, its CLEAN, and you will be surrounded by a great community that push you through the workouts.

I've achieved a total body recomposition--losing 9.7% body fat and gaining lean muscle--all while consistently hitting the gym 4x a week. ​Coming in as someone completely new to CrossFit, I was a bit nervous, but Coach Dan and all the other coaches and members are so nice and welcoming. It truly feels like a supportive community. ​The biggest shift for me was my nutrition. Before starting, I wasn't eating enough calories or the right macros, which left me feeling bloated and sluggish. Since starting this nutrition journey, I've learned how to fuel my body properly. I'm actually consuming more calories now, but doing it the right way has completely changed how I feel. ​I've been on several vacations since starting and was able to enjoy myself without worrying about putting the weight back on. This nutrition plan is truly about balance. The best part? The clothes that didn't fit me for the longest time have finally moved to the front of my closet, and I feel so much more confident in my body. I have more energy and strength than ever before, and I can't recommend Coach Dan enough!"
