    Walking for Weight Loss: Why Zone 2 Cardio Works

    Zone 2 cardio — exercise at 60-70% of maximum heart rate — has gained significant attention for its unique metabolic benefits, including improved fat oxidation and mitochondrial function.

    The Walking Sweet Spot

    For most adults, brisk walking at a pace where conversation is possible but slightly labored falls squarely in Zone 2. Daily 30-45 minute sessions yield substantial benefits.

    Stacking with Other Training

    Zone 2 walking pairs exceptionally well with resistance training, providing recovery while still driving meaningful metabolic adaptation.
