At 5am I'm at the trailhead where I walk 5 miles a day with a 30lb backpack and a 10lb rifle in my hands, no sling. I do that 6 days a week.
On completing that I'm back at the trailhead. If the ground is dry or frozen I drop and do 40 pushups with the pack on, then shed the pack and do 40 crunches. Otherwise, its a drive back to the shack.

Back at the shack I do 40 more pushups and crunches. After that I'm ready for the rest of the day.

It's you and the bullet, and all the rest is secondary.
