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.

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.
