Fat loss
Zone 2 Cardio for Sustainable Fat Loss
Low-intensity steady cardio that improves metabolic health and burns fat without trashing recovery.
- Duration
- Ongoing, 8+ weeks
- Days / wk
- 3–4 cardio sessions
- Equipment
- Bike, treadmill, elliptical, or pool
- Difficulty
- Intermediate
Zone 2 — conversational-pace cardio at roughly 60–70% of max heart rate — is the foundation of every elite endurance program for one reason: it builds mitochondrial density and fat-oxidation capacity without spiking cortisol or interfering with strength training.
Who it's for
- Lifters who want cardio without losing gains
- People with high stress who can't tolerate hard HIIT
- Anyone targeting metabolic flexibility
Core principles
- 1
Stay where you can hold a sentence but not a paragraph — that's Zone 2.
- 2
Use a heart-rate monitor for the first month; perceived effort underestimates Zone 2.
- 3
Pair with 2–3 strength sessions, not on the same day if you can avoid it.

FAQ
Why not just do HIIT?
HIIT is time-efficient but expensive on recovery. For people in a calorie deficit (especially on a GLP-1), Zone 2 produces similar fat-loss outcomes with much better adherence and fewer injuries.
