About
Looking to lose weight, build muscle, get stronger, or feel more confident in the gym? I’m Nick Martin, founder of Kryptonian Muscle, and I’ve spent over 10 years helping clients throughout St. Louis reach their fitness goals through personalized training, nutrition coaching, and sustainable lifestyle changes. I know what it’s like to struggle with your weight because I’ve lived it myself. I lost over 100 pounds naturally, and that transformation sparked my passion for helping others do the same. Whether your goal is losing body fat, building muscle, getting stronger, improving your athletic performance, or simply becoming more confident in the gym, I believe the best results come from a plan that is built specifically for you—not a cookie-cutter program. What I Can Help You Achieve ✓ Weight Loss & Fat Loss ✓ Muscle Building ✓ Strength Training ✓ Nutrition Coaching ✓ Sports Performance ✓ Powerlifting ✓ Sustainable Lifestyle Change For over 10 years, I’ve helped clients throughout St. Louis work toward goals ranging from their first experience in the gym to preparing for competitive powerlifting. My Approach Whether you’re stepping into a gym for the first time or preparing for your next powerlifting meet, your program is customized specifically for you. Training sessions focus on proper technique, accountability, education, progressive programming, and building sustainable habits—not quick fixes. My goal isn’t just to get you through a workout. I want you to understand why you’re doing what you’re doing and give you the tools to continue making progress long after our sessions together. I train clients at Output Performance in St. Louis and offer: • One-on-One Personal Training • Weight Loss Coaching • Strength & Muscle Building • Nutrition Coaching • Semi-Private Personal Training • Sports Performance & Powerlifting Coaching Why Kryptonian Muscle? Fitness should be about more than simply looking different. It’s about becoming stronger, more confident, healthier, and more capable in everyday life. Because I’ve personally gone through a major transformation, I understand how challenging it can be to make lasting changes. My approach combines real-world experience with individualized programming, coaching, accountability, and education to help you build results that last. No crash diets. No extreme promises. No one-size-fits-all workouts. Just a plan designed around you, your goals, your schedule, and your starting point. Before You Reach Out I personally respond to every inquiry and genuinely appreciate your interest in Kryptonian Muscle. My free consultation is designed for people who are seriously considering personal training and are ready to discuss their goals, schedule, and budget. If you’re still comparing your options, that’s completely okay. I simply ask for open communication so we can determine whether we’re the right fit for each other. Your first consultation is completely FREE, so we can discuss your goals, answer your questions, and determine the best plan for your success. Let’s build a stronger version of you.

Training with Mr. Nick at Output Performance has been a great experience thus far. He is very motivating, understanding, and always pushes you to do what you don’t think you’re capable of. His workouts are challenging but they have great results, and he makes sure you are doing everything with the correct form. The workouts are created based on your goals, everything is intentional and purpose driven!

He creates a positive and supportive environment that makes working out enjoyable. Since
training with him, I’ve noticed improvements in my strength and overall fitness that I didn't notice before. I would definitely recommend Mr. Nick to anyone looking for a great trainer.

Nick is an excellent trainer! Not only does he know his stuff, he's a super fun dude to be around and makes training fun. I don't think I could recommend anyone else.

I started
training with Nick about 1 year ago. In that time I have seen massive gains in not only muscle size but endurance and strength as well. I was also able to drop from 26% body fat to 17% body fat in 11 months while gaining several pounds of muscle at the same time!

The programs that Nick creates are customized to each person's individual needs and will absolutely provide you with the results you are looking for, provided YOU put in the effort!

If you're thinking about bettering yourself and getting in the gym but are shy or nervous about walking into a new environment, start
training with Nick ASAP. He will make sure you're comfortable and will always push you in the right direction!

I’ve been working with Nick for nearly a year and am now much fitter, stronger, and healthier. I’m seeing a steady reduction in the aches, pains, and stiffness caused by sitting at a desk for decades.

Nick tailors each session to ensure that I work just hard enough to get results, but not so hard that I get injured or sore. I’ve worked with several
trainers and have seen the best results with Nick. He’s easy to work with and always willing to accommodate my unpredictable schedule. Highly recommended!

Nick has worked with me finding the perfect work out program to push me and build me up to be physically better. He has changed my routine to best work with my strengths and strengthen weaknesses.

After having surgery that took me out for a few weeks Nick changed up the program to get be back in the gym and build up my confidence to get back at it.

Would highly recommend him for beginners and gym veterans that just need a little help with motivation!
