Strong and fit. Not one or the other.

“I didn't shrink. I reforged.”Luke Fullbrook

You don't want to be 65kg running a 3-hour marathon. You want to be 90–100kg: strong enough to protect your family, fit enough to run all day, and healthy enough to do both for the next 40 years.

Most programmes make you choose. This one doesn't.

The method

Four pillars

  1. Structural Armour

    Keep the muscle you spent years building.

  2. Engine Capacity

    Aerobic fitness that runs deep. Mostly easy, some threshold, never junk.

  3. Functional Strength

    Lift heavy, carry heavy, move heavy. A carry in every strength session.

  4. Longevity

    Train to be 70 and still lifting. Nothing here trades your joints for a number.

The plan

The REFORGED benchmark

You do it in Test Week and again in Week 12, with the same weights in the same order. The gap between the two times is your result.

  2. 50 kettlebell or dumbbell swings
  3. 40 push-ups
  4. 30 goblet squats
  5. 20 pull-ups or rows
