Understanding Your Result

The calculation generated by this tool provides an evidence-based assessment derived from established physiological and clinical equations. Use this measurement as an educational indicator alongside broader lifestyle variables, including overall dietary quality, resistance training, cardiovascular endurance, and routine medical checkups.

Mathematical Formula & Scientific Methodology

Workout energy expenditure uses modality-specific MET factors: Heavy Strength Training (MET 6.0), Circuit/HIIT (MET 8.0), Vigorous Cardio (MET 8.5), Vinyasa Yoga (MET 3.5).

\text{Calories} = \left(\frac{\text{MET} \times 3.5 \times \text{Weight (kg)}}{200}\right) \times \text{Minutes}

Step-by-Step Example Calculation

A 75 kg person performing 50 minutes of HIIT (MET 8.0): Calories = (8.0 × 3.5 × 75 / 200) × 50 = (2100 / 200) × 50 = 10.5 × 50 = 525 kcal.

Clinical Limitations & Nuances

Rest periods between sets reduce average MET in strength training; our calculator accounts for standard inter-set recovery intervals.

Frequently Asked Questions

Does weightlifting burn calories after the workout ends?

Yes. Heavy resistance training elevates post-exercise oxygen consumption (EPOC), causing modest additional calorie burn during the 24-48 hour recovery window.

Is HIIT better than steady-state cardio for fat loss?

HIIT burns more calories per minute and triggers higher EPOC, but steady-state cardio is easier on joint recovery. A combination of both is optimal.
