Welcome to
​Calloused fitness

Calloused Fitness first opened doors in late 2008, in the basement of a 3 bedroom home in rural Iowa. Since then, the gym has grown to accommodate members in ​a private specialized "garage gym" and more conveniently - virtually.
​
Calloused Fitness and its members value strength. We collectively focus on building and becoming a stronger version of ourselves rather than trying to shrink our bodies or ourselves to conform to whatever societal pressures might have us believe we should act or appear as.

What members are saying

Tammy 

Local & Underground Athlete

I suffer from a skeletal and muscular disease. When I first started training with Katie, I couldn't get myself up off the floor unless I rolled over on my belly first and used my hands and knees. I couldn't jump to a 1/2 inch plate on the ground, now I can box jump 24". Now I'm more flexible and stronger too.

Mauve

Underground Athlete

On occasion, I would perform workouts by myself but usually found it hard to be consistent or plan what to do before I get to the gym. Luckily, I found Underground Athletes. Katie encourages and holds me accountable, regardless of whether I choose to complete the workouts at home or in a fully equipped gym. I can't believe the program costs only $5 per month, and it provides the benefits of gym membership, scheduled workouts, coaching, and a supportive community.
