Our newest secret weapon: Revealed.
After a trip to one of the coolest gyms In Vegas in June and using this machine, I knew our gym absolutely needed it. Within 48 hours, I had an order put in to have one custom built for us.

This single leg hamstring curl machine is easily one of the best ways to target that glute/ hamstring tie in. Full isolation, while also being in an ergonomic and comfortable position with the non working leg. The ability to also quickly pivot the knee support makes switching sides seamless.

Not to mention that beautiful, black powdercoat 😍

I can not wait to see our bodybuilders on this machine, leveling up what they bring to the stage at their next show.

SUPER exciting news!!!

We have literally been waiting nearly a year for this announcement. It's happening. Our partnership with an "In-House" physical therapist next to Grit 44!!

September is an exciting time for Integrate Wellness, it marks the 6 month milestone of having our doors open! When Integrate Wellness was just an idea, we had a dream of providing a safe space for recovery for the whole person; including the mind and body as we believe that each go hand in hand in supporting people in our community in achieving their personal goals. Our vision of providing a place in the Black Hills where people feel at home with their recovery wellness journey and our mission of recovery for the mind and body reflect this dream. To continue to work towards that dream, we are excited to announce the addition of Physical Therapy to Integrate Wellness! Austin Frybarger will be opening her schedule up in October for patients in need of physical therapy. With our collaboration with 605 Grit Fitness and Grit 44 along with mental and physical therapy under the same roof, we are very excited to see our dream of providing recovery for the mind and body come true and take shape! So, if you’re in need of mental support, physical support, or both we are here for you!
Stay tuned for more details and more exciting things coming!

You love us, you really love us 😭😭😭
THANK YOU Black Hills, Grit Fam, and everyone who took the time to vote for us TWO years in a row as your favorite Gym in the Black Hills! We wouldn't be here if it wasn't for you. Our members are still the reason we have been able to provide excellent service all these years. It's an absolute honor.

I want to also give a huge thank you to our staff, and our personal trainers. They have committed to Grit and to our mission, and have always shown up for the gym, and their clients. Always putting the clients and members goals and needs first. We seriously have to beat staff here.

Okay I'm going to stop crying now and go do some curls or something. 🥸

We will keep pushing the boundaries of what a gym can look like, feel like, and be like. Stay tuned, there are massive things in the works. -Owner Michael Brown
