    I've been training with Marilyn since November 2023, and the results are showing! What sets Marilyn…read moreapart is her truly tailored approach to my specific needs and situation. She took the time to understand my goals, limitations, and preferences, and consistently challenges me (to the point that I also challenge myself now!). Marilyn is also an incredibly cool and down to earth person, who truly makes the journey easier! I've never consistently worked out in my life and this couldn't be a better fit (personality wise), as she doesn't make you feel like you're the one being trained- more so like you have a partner in the workout journey. Her positive attitude and encouragement keep me motivated and engaged- I went from twice a week to nearly every weekday. I highly recommend Marilyn to anyone looking for a dedicated and effective personal trainer who genuinely cares about their clients' success and brings a fun, positive vibe to every workout.

    I've been training with Marilyn since the end of June 2024, and I'm so happy to have her in my…read morelife! I'm almost six months postpartum, and training with Marilyn has become one of my favorite parts of the week. One of the best things about our workout sessions is that I can bring my baby along. As a new, first-time mom, finding time to work out is a huge challenge, and if it weren't for Marilyn, I don't know how I'd manage. Not only is she super caring and sweet, but she also pushes her clients to do their best. I always leave feeling like I got an incredible workout, and she tailors everything to my comfort level. I sometimes do Peloton workouts at home, but it's just not the same as working out with others or having a trainer who holds you accountable. Marilyn even provides a fantastic meal plan and an app to help track calories and offers home workouts through the app, which makes it super convenient. She also takes measurements at least once a month, which really helps me stay on track. Plus, she looks amazing, which is so motivating! Since training with Marilyn, I've lost about 10 pounds, and my body fat percentage has dropped by 4.6%. I know if I were stricter with my calorie intake, as Marilyn recommends, I'd likely see even more results, but my main focus right now is just moving my body and having fun! My baby and I genuinely enjoy every session, and we've met so many lovely ladies. I'm so grateful for Marilyn and everything she does--if you're looking for an amazing, affordable trainer, I highly recommend her!

    I'm scared to write this review because more people will want to join this hidden pittsburg gym …read more As much as I want to keep it a secret this gym needs recognition. 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!

    This group of people is amazing and this gym is amazing…read more I moved to this area and I had never done CrossFit before but Matador Fitness was the closest gym to my house. 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.

    This review is long overdue. I started my fitness journey 6 years ago and I've been in and out of…read morevarious gyms depending on where I live and where I work. I have to say out of all the gyms I've been to: FBBC, UFC, Planet Fitness, The Camp, and many other local family owned gyms, Concord fitness boot camp aka Fit Body Boot Camp concord has been the absolute best! I lost weight but the change was not just in appearance. I actually felt stronger and could notice the difference in my strength. My energy and endurance was like my teen days. The crazy part is appearance wise this gym has been the least impressive. But Virgil makes the small space functional and you really don't need much more than this. When I showed up for my first trial the location made me hesitant. Virgil's customer service was great and he made me feel welcomed. The other members were friendly and there were all ages and body types. I stayed and loved it. Everyone was extremely helpful and motivating. They all push you to finish your reps, to keep moving and not quit, and if you struggle they make you feel okay with modifying while teaching you ways to work on it until you can one day do what you're struggling with. It was hard but it seemed like within days my body learned how to handle doing sit ups and push ups. Another major part is nutrition. Virgil helped me with a shopping list and meal ideas. He is respectful but also doesn't sugar coat. With each weigh in he reminded me what I needed to do to stay on track. I also learned how to count calories. If I still lived in the area I would see about joining again. If I didn't give it 5 stars it is solely because of the cost. When I went it cost around by $300/month. Is it worth it? Yes. Is it affordable and feasible? No. I could not keep up going there as it was too much for my budget. Pictures for comparison of cheeks and chin when I first started in March to September

With reassurance from the owner (whose phone number was on Google), it was indeed open for business, I was excited to get moving for my Friday workout. I was introduced to the owner and other people who showed up for the class and I could tell they were regulars. The place looked pretty legit as you know I love legit gyms :-) I was asked to disinfect the bottom of my shoes as street shoes aren't allowed on the floor, since we laid on them for floor workouts. That made me feel better because I ain't tryna rest my head on a floor where people before me don't know where to walk sometimes and you don't know where they come from ahem, SF CITY STREETS!!! This was my first Bootcamp class in a long while so I was pretty thankful that Virgil (owner and trainer) allowed me to modify my workouts. It was a damn good sweat and I had great energy the rest of the day.

    I completed the program and lost over 20 pounds in 6 weeks, which I'm very proud of. The challenge…read morehad a clear structure with guidelines around meal timing, protein intake, and food combinations, and I did see strong results when I followed the plan closely. The nutrition portion would have been even more helpful with clearer explanations of the reasoning behind the guidelines, as well as earlier access to that information prior to committing to the program. At times, there also seemed to be some inconsistency between the food guidelines shared in different places, which made it a bit difficult to know what was best to follow. The program does require a high level of consistency, and my cohort of 3 was smaller than expected, so it didn't always feel like a shared group experience. That said, the coaching staff was a highlight--Gabby and Felicia were excellent, and the gym environment is very positive. Overall, it was an effective way to kickstart my return to fitness, and I would continue attending classes at the gym in the future.
