If you’re here, I’ll bet you’re looking for a change. You may even be looking for a total transformation: of your body, of your behaviors, and all the things affected by your fitness – performance in life, energy levels, confidence, friendships and more.

FIRM in 42days is Grit Gym's total body makeover program. This challenge was created to provide a comprehensive training program for our friends to tackle their big obstacles stopping them from the health and exercise experience they want.

You see, our friends and clients wanted to get results. They wanted to lose weight, have more energy, and generally feel awesome. But they weren’t able to stick with the restrictive or poorly designed programs they tried. Or they’d try working out on their own, but were never quite sure what to do. And in many cases, they’d get injured before seeing the results they were working for.


*ONLY 12% of the USA has a gym membership

*ONLY 8% of the USA gets enough activity to benefit from that activity

*Over 50% of the those who join a training gym this year will get injured

*Over 40% of the USA is obese

*87% of the USA has some kind of spinal stenosis

*We are Free of the nature forcing us to be in shape, but we are not Free of the Responsibility we have to our bodies need for activity, good food, rest and mindset.

Grit Gym started out of the chaos of this industry. People we cared about were negatively affect by those not caring enough to listen, learn, and use an evidence-based approach with strategies that ACTUALLY work. We heard horror stories about friends getting shouted at or shamed by bootcamp drill instructors with minimal actual education on human physiology that never took the time to assess them as individuals to find what was best for them, or to teach technique in a way so they could make progress without injury. 

Nobody should have to put up with that.

The FIRM in 42days program was made to get results, and also educate in a way that really works for health that will last the long haul. On top of that, to do so in a way that’s so fun people wouldn’t know how much work they were doing. 

Getting in shape is hard. You deserve to work with actual experts who will challenge you while encouraging. You deserve the best.

“I could just say "Grit Gym Rocks!" and leave it at that :) 

The benefits of working out at GRIT Gym go beyond the physical. In addition to improved strength and fitness, you gain a sense of accomplishment and increased confidence which stick with you throughout everything you do.

The personalized workouts are carefully crafted to help you become stronger and more fit, but Grit Gym also fosters an atmosphere of encouragement and positivity that makes even the toughest workout enjoyable.”


"I have been going to Grit Gym for over 2 years now.  My main reason for joining was as I was getting older I wasn't happy with how my body was responding to the daily things, e.g. getting out of bed in the morning and my back hurt, doing simple yard work and I was sore as heck the next few days.  So I made the decision to join after doing some research, and couldn't be happier with the results. 

All of the trainers (Adam, Tori, and Eric) are excellent.  They explain each exercise and emphasize correct form.  The classes are the right size and the other members are awesome.  I truly believe Grit Gym is the best.  Do yourself, your body, and your mind a favor and check them out.  You won't be disappointed."


"At Grit Gym a coach sat down with me and figured out where I needed to start and which exercises would best for me. We focused on what I could do with a healthy respect for what I should avoid. 


The program was tailored to me so that my efforts would be working FOR MY body. I could get stronger without getting hurt and that way I can experience more of what I love to do. Like playing with my grandkids. I'm a young grandma. When the kids stay over I can carry them upstairs to bed when they fall asleep. It's easy to find motivation to do deadlifts and push a heavy sled when you remember how much it helps you do what you love most. 

I see my mom having trouble getting up stairs, out of a chair and how quickly she gets out of breath walking. It kills me to see that. And I'm so glad to have this place, a program ready for me when I walk in and someone there to help me with each exercise. It's one of the absolute best parts of my day."
