The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

Write me a 30-minute easy Zone 2 cardio session for someone whose main goal is building muscle, to do on a non-lifting day or after weights. Keep it genuinely easy and conversational (heart-rate Zone 2, able to hold a conversation) on a bike, incline walk or elliptical to keep impact low, with a 5-minute warm-up and cool-down. Keep cardio mostly low-intensity and separated from heavy leg days so it doesn't interfere with strength and size. Give each block a duration and a target heart-rate zone.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Moderate cardio doesn't harm muscle growth when it's mostly low-intensity, kept to sensible volumes, and separated from heavy leg training — the "interference effect" mainly shows up with high-intensity running done close to lifting. Easy Zone 2 work improves recovery and heart health while you build.
