according to andy galpin, how much moderate cardio exercise should you do?

Andy Galpin’s recommendation is about 150–200 minutes of moderate, conversational-pace (zone two) cardio per week. 1 2

• General cardiovascular-health target: Huberman describes 150–180 minutes per week as a broad target, while Galpin’s stated range is 150–200 minutes. 3 2
• Walking: Walking is beneficial physical activity, but Galpin distinguishes it from structured exercise; a walk may be zone one or sometimes zone two, so easy walking alone may not provide the full moderate-intensity cardio target. 4
• Muscle growth: Galpin says conversational-pace zone two cardio is unlikely to meaningfully interfere with hypertrophy for most people. 5
