ISSA Certified Personal Trainer, Nutritionist & Manager of Xtreme Fitness
​
With over two decades of hands-on experience, Grant is a veteran in the health and wellness industry and currently serves as the manager of Xtreme Fitness. His diverse background spans martial arts, gymnastics, bodybuilding, body tempering, corrective exercise, and injury prevention — giving him a versatile and functional approach to fitness that’s as educational as it is effective.
​
Grant’s passion for health started young, growing up in gyms alongside his father. Living with an autoimmune disease eventually deepened his interest in nutrition, pushing him to become a nutritionist in addition to his work as a trainer. This personal journey fuels his mission to help others — whether they’re navigating health challenges or simply looking to level up their fitness.
​
Beyond one-on-one training, Grant has organized martial arts mountain summits, hosted educational clinics, and led personalized consultations — all centered around sharing knowledge and empowering others. For Grant, training is about more than just reps and results. It’s about building a strong foundation and understanding your body.
​
To reach even more clients, Grant also offers remote coaching through his online training app, Arsenal Fitness LLC, where he provides both standard and fully customized programs tailored to individual goals. For those seeking a flexible, cost-effective option, he also offers hybrid training — a blend of online and in-person coaching designed to maximize results while minimizing cost.
​
As he likes to say, “I’m just a nerd with muscles that hopes to help others towards building their arsenal of knowledge.”
Whether you're starting your fitness journey, recovering from injury, or seeking advanced training, Grant’s depth of experience, personal insight, and commitment to education make him an exceptional partner in achieving your goals.
What Grant's Clients Say
Teresa T.
Before working with Grant Rose, I was in constant pain, my back, hips, knees, and shoulders all hurt. My shoulders were so weak I couldn’t even lift them if I was holding something heavy. But now, the pain is gone, and my shoulders are much stronger. Grant is incredibly knowledgeable, and the results I’ve seen are amazing. He pushes me to my limits while always making sure I’m safe. Honestly, I would still be in severe pain if it weren’t for Grant, my doctors had no idea what was going on, but he did.
