Diet and routine vary a lot. Routine is based around functional movements deadlifts, squats, power/hang cleans, jerks, weighted pull ups, heavy kettle balls, bench, Russian twists, weighted planks, hitting things with a sledge hammer, etc. all throughout the week. Then when I have time/feel like I need it I throw in some extra iso movements.
Diet: A sample day is:
12-16 whole eggs for breakfast, with a glass of raw milk, and a slice or two of whole wheat toast with raw honey and butter.
For lunch some grilled salmon or chicken with some greens.
And then some source of a lot of protein a lot of steak, or 7-10 hamburgers (6oz each, just the meat no bun, and usually no cheese), or a lot of fish, or seafood like Lobster.
Then some times a late night snack of raw milk with some frozen blueberries, or some yogurt.
That's really the only kinds my family has around the house, so I grew up eating like that.
