My initial physical exam required me to run in place for some short period of time, then touch my toes, close your eyes and move your head in a circle. I then stood on a scale and pulled up on a handle to see if I could lift some amount of weight, which I forget the target weight. After that first physical exam I never repeated those exercises for any subsequent DOT medical exam. We were required to go to the doctor the company picked for us, not just provide a new DOT medical card before the last one expired.
I liked Averitt and worked for Nissan Dedicated near Nashville for 18 years. The pay was rather low, but everything else was calm and predictable and stable. Boy Scouts only, no cowboys.
