 Verified Holly's studio is bright and well equipped and her methodology is great.  However, the best thing about this studio is the wonderful trainers.  I have been working with Jade for almost two years and she is amazing.  I was in poor shape when I first started but with  Jade's guidance and encouragement I have achieved my goals.  I have lost weight, improved my strength and flexibility and improved my overall health.  Each workout is different and meant to work all my muscle groups - Jade keeps things fun and challenging.  Than you Jade!

  I started strength training here 3 years ago, right after retiring. I get personal training in a semi private small group and it has been a wonderful and very positive experience. When I first started, I was struggling with weights and core strength, but I have seen a marked improvement over time. The instructors are supportive and flexible with routines, so if you are injured in one area they can give you other options.

 Verified Nothing but positive things to say about the studio. I started training here three years  not being a regular gym person but since I just retired, I had no excuse. I do strength training in a semi private group. All the trainers are excellent, especially Jen, who has been outstanding! I have definitely seen an improvement in my physical capabilities and core strength.

  So I went from 391lbs as of 11/21/25 to 281lbs as of 6/25/26, and I attribute a huge amount of my successful weight loss to Holly Roser Fitness. For a long time, my doctor’s had been trying to advice me to get into a medically supervised route to weight loss (GLP-1 Medications, Bariatric Surgery, the usual..). Thanks to Holly, her husband, Jonathan, and another fellow trainer Brian, I have been able to dodge this and lose my weight organically. Holly and Jon, don’t just give you the core fundamentals you need through exercise, they go above and beyond. Jon has helped ensure my form is correct to absolutely avoid injuries, and always answering any questions I have. They also ensured I got the right shoes, and the right equipment, and for the right price, to be successful at home by myself. Brian also focuses on fundamentals and makes sure you understand why you’re doing what you do, and always is patient. Holly and Jon, both don’t sit there and promise a magic wand to you. They promise results through discipline, great nutritionists, and a scientifically driven mindset towards exercise. If you expect to just go in for your session and lose weight, not going to happen. Listen to their advice, do the weekly sessions with dedication and be dedicated to your diet and your own cardio/strength work and you will get results. Thank you Holly and Jon, I owe this new phase of my life to your constant belief in me, and constant support.

  I just have to share how amazing Holly Roser in San Mateo is! She and her team are incredible — so friendly, motivating, and professional. Every trainer I’ve worked with knows exactly what they’re doing and makes you feel supported the whole time. Since I started training there, I’ve seen real results. I feel stronger, healthier, and more confident, and I honestly can’t imagine my routine without them anymore. If you’re looking to lose weight, tone up, or just feel healthier overall, this is the place to go. They make fitness fun, challenging, and totally doable, no matter your level. I can’t recommend them enough — if you’re serious about reaching your goals, you have to check them out!

 Verified I can't say enough good things about my trainers at Holly Roser -- they are absolutely amazing! They create custom workouts that actually work for me -- every session is tailored to my goals and my progress. What really sets them apart is their encouragement. They know exactly when to push and how to keep me motivated, even on the toughest days. They somehow make even the hardest workouts for me feel like fun. On top of that, they are incredibly knowledgeable. Whether it's form correction, recovery tips, or nutrition advice, they always know what they're talking about. I feel stronger and healthier.

  I found this studio during my detailed search of training studios in San Mateo. It was a plus they had small classes consisting of women. I needed a safe place to train slowly since I’m deconditioned. My goals are to get stronger and also lose weight. I’m not disciplined enough to go through the gym regularly on my own. I had a FaceTime call with Holly and we discussed all of my goals and how she and her team can help me. I felt she really listened to me and we created a plan. I came in for a 1 on 1 and loved the studio. I’ve completed 10+ semi-private sessions now and I’m excited to continue. All of the trainers are so supportive and really help me perfect my form during the exercises which I wanted. I’m feeling stronger already and feel motivated to continue exercising on my own when I’m not at the sessions. They also offer meal plans and nutrition help which I’m considering. Overall would highly recommend to anyone. It’s definitely worth checking out.
