Zone 2 is the easiest training you’ll ever do, and the one most people skip. It’s the pace where you can hold a conversation — a brisk incline walk, an easy bike ride, a slow jog you’re mildly embarrassed by.
Why bother going slow
Two 30–40 minute Zone 2 sessions a week measurably improve recovery, blood pressure, and how you feel at 4 p.m. on a Tuesday. For busy adults it’s the highest return-per-effort training that exists — and it stacks on top of strength work instead of competing with it.
How to make it not miserable
Attach it to something you already do: walk the call you’d take at your desk, bike while you watch the show you’d watch anyway, take the stairs meeting. Cardio you don’t dread is cardio that actually happens.
