Why Zone 2?

It's how the pros build their aerobic engine.

  • 80/20 Polarized Training

    Elite cyclists spend 80% of training time at low intensity. Zone 2 is where base fitness is built.

  • Fat Adaptation

    Train your body to burn fat as fuel. Improve metabolic flexibility and endurance capacity.

  • Mitochondrial Growth

    Zone 2 specifically targets mitochondrial biogenesis. More mitochondria = more power.

  • Sustainable & Enjoyable

    Easy effort means you can train more frequently without burnout. Build volume, not fatigue.
