Jeremy Ethier: I Ran Everyday For 30 Days, It Changed My Life

Key Takeaways

• Run in Zone 2: Train at 60-70% max heart rate (120-140 BPM for Jeremy) for 45-60 minutes to improve fat-burning and lactate clearance.
• Time cardio strategically: Do cardio after weights or later in the day to avoid energy depletion during strength training.
• Refuel with carbs: Eat quick carbs (bananas, rice cakes) before workouts and complex carbs (potatoes, rice) post-workout to counter calorie burn.
• Protect leg days: Avoid long runs before leg workouts to prevent muscle fatigue compromising strength training.
• Try Norwegian 4×4 method: 4-minute max effort cardio bursts followed by 3-minute recovery, repeated 4 times for endurance gains.

Products & Gear Mentioned

• MRI scans: Used to precisely measure muscle changes pre/post 30-day challenge.
• VO2 max test: Assessed baseline cardiovascular fitness.
