I work out often in the gym with weights and treadmill, I know that some truckstops have facilities but how easy will it be to find a gym at least 3-4 times a week? Thanks
Not often if at all at truck stops.
Join the YMCA and you will have ability to find a weight room. Many YMCA's will honor your membership from your local one.
Stopped at Sears and bought their version of the total gym. I just set it up in the back of the truck a couple times a week as time allows. When I'm not useing it, it folds up out of the way with the rest of my stuff.
