Finding Coach Marvin from Martian Fitness on Thumbtack was honestly the biggest luck I've had this year. I wasn’t sure what to expect at first, but from day one, he completely changed how I see training. He’s patient, insanely knowledgeable, and somehow makes you believe you can do way more than you think. If you’re tired of fake trainers and actually want someone who cares – Marvin is the one. Thank you, really. 🙌

Marvin’s personal training has been truly transformative for me. Not only have I seen incredible physical progress, but his coaching has completely changed my mindset around fitness and nutrition. He focuses on building sustainable habits rather than quick fixes, which has helped me develop a healthy, balanced relationship with working out and fueling my body. I feel better overall; I feel stronger, more energized, and more confident and I actually have fun at the gym now, which I never thought I’d say! Marvin is knowledgeable, supportive, and truly invested in his clients’ success. I can’t recommend him enough.

I highly recommend Marvin as a personal trainer. We’ve been training with him for over three years, and he’s been nothing short of amazing. He’s extremely responsive, truly cares about his clients, and has a way of holding you accountable while still being supportive. Over time, we’ve also built a great friendship, which makes working with him even better. His workouts are always challenging and never repetitive—he constantly mixes things up to keep you progressing. Thanks to Marvin, I’m in the best shape of my life. He consistently measures and tracks progress, which makes a huge difference and keeps you motivated. If you’re serious about results, Marvin is the trainer you want.

I’ve worked with Coach Marvin for years, and I can confidently say he’s one of the best personal trainers out there. He genuinely cares about his clients—not just their fitness goals, but them as people—and over time he’s become a great friend as well. He’s incredibly responsive, always supportive, and truly invested in helping you succeed. His workouts are tough (and yes, sometimes painful), but that’s where real growth happens. I was in the best shape of my life while training with Coach Marvin, and I’m so happy to be working with him again. If you’re looking for a personal trainer who pushes you, supports you, and actually cares about your progress, Coach Marvin is the one.
