Welcome Lyman!
I am in a similar boat as you, in that I work about 12 hours a day on average and travel 20 hours a week. It is very hard for me to find time to hit the gym and exercise, but I just have to force myself to do it and make it a priority. I still don't get to exercise as much as I would like in an ideal world, but every little bit helps
.
Good having you here and best of luck on your journey!
