Check out First Due Fit Training
From their website:
First Due Fit Training is a firefighter owned business that provides challenging workouts that are related to the job of firefighting.
Recognizing a void in the fire service, we created First Due Fit to match the “aggressive” culture that is prevalent in the fire service with various physical fitness programs designed to match the physical needs of us on the fire ground.
We have created multiple workout programs for various fitness levels, including those who have not workout out in years to get you to where you need to be, to those who are advanced and take physical fitness seriously.
Go check them out!!
