A lot. Mostly zone 2 running but also quite a bit of hill work and some rucking. An occasional mountain bike ride if/when friends ask and I can make it work. Some swimming in the summer. And I walk a lot, like 15k steps daily on top of the running.

Specifically, I follow the Tactical Barbell hybrid training system. Most of my training these days can be lifted directly out of the Tactical Barbell Green Protocol book, but I also incorporate training from the original Tactical Barbell strength book, the conditioning book, the Mass Protocol book, and the Ageless Athlete book.
