About
I’m Mark, a San Jose personal trainer with 7 years of experience and the owner of Muscles By Mark. I’ve competed in men’s physique, and today I train for marathons and compete in HYROX Pro, so I know how to build muscle, build endurance, and balance the two. I work with people who are done guessing in the gym and want a plan that works, whether that’s your first HYROX, your first 13.1, or getting stronger and leaner. What you get: • A program built around your body, schedule, and goals, not a generic template. • Physique and strength coaching from someone who’s taken a physique to the stage: smart training splits, progressive overload, and nutrition habits that stick. • HYROX and endurance programming that balances running, strength, sled work, and recovery. • Direct, honest coaching. I’ll tell you what’s working and what isn’t. • Options that fit your life: private 1-on-1, semi-private, or small group. • Accountability: making sure you show up to make your goals happen. If you’re ready to put your goals into action and take it to the next level - send me a message and let’s talk about how we’ll get there.

Its not easy finding a good trainer. Ive been through my fair share and Mark really exceeds any expectation for training and personal fitness. He took time to really understand my needs and my limits but he also knows where to push those limits when necessary - he pays attention and knows his stuff. He made me feel comfortable with all the equipment beyond what any other trainer has done for me, which is huge because working out in a gym can be intimidating but he really trained me for the long term and comfort with all the future tools I would need - beyond our sessions. My strength went to new limits and hes also just a great person! My mother in law also trained with him, thats saying a lot when a trainer can adapt to my whole family. Highly highly highly recommend Mark for any fitness needs !

Mark and I connected at Miro when he was the fitness director. I told him my goals and told him I lacked accountability. Boy did I make that error because he MADE SURE I got my work outs in and achieved my goals for my event in record time. Mark is attentive, kind, professional, supportive and very knowledgeable. I recommend Mark for your fitness goals. You want to be healthy, fit, banging body - Call Muscle by Mark!!!!!

I have been working out for over 8 years, trying to build muscle and maintain my weight. Throughout my experience with multiple trainers, I found Mark to be one of the best, most professional, and funniest personal trainer also a genuine human being. His training approach is very targeted, and he knows what he's doing. He doesn't guess like most trainers in this industry; he relies on data and tracks it for his clients, which is impressive. I wish him the best of luck in expanding his personal training practice.
