POWER
Train the engine.
What it trains · Metabolic intervals, fast-twitch recruitment, repeatable intensity.
Short, strong intervals — the walks that prove walking can be a real workout. Power sessions push effort into the 7–8 / 10 range in controlled bursts, then recover fully before the next push. The point isn’t to crush you. The point is to train the engine: cardiovascular capacity, metabolic flexibility, and the kind of repeatable intensity that holds up over years.
