A physician buddy asked me whether the general population should focus on cardio or lifting — and I wanted to share my answer with you. In this solo cast, I break down why cardio and resistance training produce different adaptations, offer my go-to weekly framework for getting started, and talk about zone two training, high-intensity intervals, VO2 max assessments, and why compliance beats the perfect program every time. Plus, the Flexible Meathead Cardio Course is open for enrollment through Wednesday. Sponsors: Fitness Insider Newsletter: https://miketnelson.com/ Enroll in the Flexible Meathead Cardio course.
