ELITE PERFORMANCE COACHING
A systems-based approach to personal training that combines expert coaching, movement assessment, and muscle health principles.
SYSTEMS-BASED TRAINING
We redefine personal training by integrating muscle health science with high-performance strength coaching.
At Gunstorm Muscle Health, personal training is built around more than simply putting you through workouts. Our coaching system combines exercise science, structured strength training, movement assessment, and a muscle-health focused approach to help you train with purpose, precision, and long-term direction.
Every client begins with a personalized understanding of their training history, current fitness level, movement quality, injuries or limitations, goals, schedule, and experience in the gym. From there, we build a plan that is specific to you – whether your goal is fat loss, muscle gain, strength, athletic performance, improved confidence, or simply learning how to train correctly.
Each 1-on-1 personal training session is part of a larger progression. We coach your technique, adjust your program as your body adapts, track your progress, and provide the accountability needed to stay consistent. The goal is not random exercise. The goal is a smarter, more professional training process that helps you build strength, improve body composition, and create results that last.
PREMIUM COACHING SUPPORT
Included with select personal training memberships, the Gunstorm Coaching App helps keep your training, nutrition, habits, and accountability organized between your 1-on-1 coaching sessions.
Personal training at Gunstorm does not stop when your session ends. Select personal training memberships include access to the Gunstorm Coaching App, a premium support tool designed to keep your training, nutrition, habits, and accountability organized between appointments.
Inside the app, clients can view their personalized training program, follow custom nutrition and supplement recommendations, track lifestyle habits, and stay connected to the coaching process throughout the week.
Built to support your in-person coaching experience – not replace it.

Results look different for every client, which is why our personal training process starts with your goals, your body, and your starting point. Some clients come to Gunstorm for fat loss and body composition. Others want to build muscle, get stronger, improve athletic performance, reduce limitations, or feel more confident training in the gym.
Our approach is designed to create progress you can see, feel, and measure. Through personalized programming, 1-on-1 coaching, strength training, accountability, and consistent progression, we help you work toward meaningful improvements in body composition, strength, movement quality, performance, confidence, and overall fitness.
For one client, success may be losing 60 pounds in 24 weeks. For another, it may be gaining muscle, moving with less discomfort, returning to training after an injury, or finally feeling confident walking into the gym. Whatever your goal is, our job is to provide the structure, coaching, and professional guidance to help you make progress safely, consistently, and sustainably.

WHAT OUR CLIENTS SAY
Discover how our elite personal training transforms lives.
I'm a retired, female in my mid-60's. Seven months ago, I wanted to make a change in my exercise routine and habits. After visiting with Gunstorm Muscle Health, I was assigned to train with Caleb. I was coming in with zero weight training experience but Caleb has been helpful, patient and encouraging. He takes time to explain the 'how & why' for various weight machines or for targeting the correct muscle group. Location, cleanliness and the staff are why I have been pleased with GMH to build on my strength.
Gunnar is an excellent personal trainer, extremely knowledgeable, and really fun to work with every week. His passion for helping others is evident in everything he does, including his M.A.T. sessions. Gunnar has helped me improve my strength and overall well-being for the past 6 years with endless encouragement! He is a true gem!!
I have been training and receiving MAT with Gunnar for 6+ yrs. He is fantastic! I'm in my late 50s. I feel strong and healthy. His skill and depth of knowledge allow him to craft workout plans for a wide variety of clients, from young high school/college athletes to older adults. And with the addition of MAT reaching your fitness goals at any age is possible. I also know Caleb, personal trainer on staff. He was able to work with my daughter when she was in dance. He was a college athlete and it's a pleasure to see him working with clients in the gym. I'm impressed with the gym's equipment, it doesn't feel cookie cutter, in this cookie cutter world. And the gym is spotless!
Gunnar and Caleb make everyone feel very welcome. The personal training services are top notch. The trainers are dedicated to making sure you meet your goals in a safe and healthy way. In addition, both Gunnar and Caleb have much more education than the average trainer in Mankato. I would highly recommend Gunstorm Muscle Health!
The machines are top notch and easy to use, but if you're looking for some help learning how to lift or maybe you're even like me who's been in the gym since high school and just wants to get in peak shape for your wedding, they have AMAZING trainers. I've been working with Caleb since July and I'm the strongest and healthiest I've ever been. Not only that, but I also feel much more confident in my knowledge about lifting weights and using the machines. Caleb has taken the time to explain why we're doing a specific lift or using a specific machine, and most importantly how to use it safely by having proper form. So if you're looking for a gym where you want to get healthier and stronger, this is it.
Great 24/7 gym with knowledgeable trainers who genuinely care about your progress. The work they do has made a big difference in how my body feels and performs. Professional, personalized training. Highly recommend.
