By FerroxLabs. Updated June 7, 2026. Categories: Health & Fitness.

Explains heart rate training zones (Zone 1 through Zone 5) with calculation methods, training adaptations per zone, and how to structure a cardio program using zone-based training. Produces a personalized zone chart and weekly cardio plan organized by zone targets. Use when the user asks about heart rate zones, Zone 2 training, cardio training intensity, how to calculate training zones, or how to structure cardio sessions by intensity. Do NOT use for running-specific training plans (use running-training-plan), HIIT workout design (use hiit-workout-design), or heart rate monitoring for medical purposes.
