Con-way Orientation Physical Questions

I am seriously considering Con-way for my first OTR driving job. At 58, I am not in the greatest physical condition, although I have begun working out to improve it. I am overweight, but my BP is good with my medication. If I were to be given a pre-hire to Con-way and go through orientation, what physical tests should I expect to have to pass? Schneider as an example has a video that demonstrates their testing. The toughest tests for me if going with Schneider would be stepping up and down a 12" stair for one minute, and having to squat under a 40" platform for a time to simulate getting under a trailer. I have tested myself on the stair step, and i am sucking wind big time after doing that, although I can complete it, so I am targeting that exercise in particular to improve upon. The squat test I should be okay on also with improved leg strength. Please let me know what I might face at Con-way so I can better prepare ahead of time. Thanks.
