Why Your Exercise Calorie Estimates Are Systematically Too High — NEAT Compensation, Dose-Response, and the Muscle Mass Advantage
Why a "200-Calorie" Strength Session Burns More Than a "200-Calorie" Run — The 24-48 Hour Muscle Repair Effect
Cardio burns calories during the session; strength training continues burning calories for 24-48 hours afterward as muscle fibers repair — and long-term muscle gain increases resting metabolism permanently. Here's what skeletal muscle actually costs at rest (6-10 kcal/kg/day), why muscle protein turnover after resistance training adds 100-300 kcal over the following day, and why the "1 kcal/kg/km" running rule is more reliable than MET values for estimating running calorie cost.
Why Your Fitness Tracker and a MET-Based Calculator Disagree About Calories Burned — and Which to Trust
Your fitness tracker says 450 calories; a MET-based calculator says 320 — for the "same" workout. Both are estimates, but estimating differently: MET values are population averages applied to your weight, while wearables use proprietary heart-rate-based algorithms applied to your measured physiology. Here's why neither is "the truth," why resistance training shows larger discrepancies than steady-state cardio, and why consistency of method matters more than which method.
EPOC, the "Afterburn Effect," and HIIT vs Steady-State: Separating Research from Marketing
EPOC ("afterburn") adds approximately 6-15% to a workout's calorie burn — real, but smaller than fitness marketing implies. Here's what EPOC actually measures, why HIIT's real advantage is time efficiency rather than metabolic magic, how HIIT and steady-state compare for fat loss, and how resistance training's EPOC differs from cardio's.
MET Values, RPE, and Heart Rate Zones: How Exercise Scientists Measure Intensity
METs let you compare any physical activity in a single number. Here's the full MET scale with specific values, the calorie calculation formula, RPE scales and the talk test, heart rate zones explained, and why fitness level makes the same workout burn fewer calories over time.
Exercise Burns Fewer Calories Than You Think — Why NEAT Matters More
Formal exercise accounts for just 5–10% of most people's daily calorie burn. NEAT — all the non-gym movement in your day — often matters more. Here's how the numbers actually break down, and what that means for fitness strategy.
