ℹ️ About This Calculator
The Calories Burned Exercise Calculator uses the internationally validated MET (Metabolic Equivalent of Task) framework to estimate energy expenditure during prescribed therapeutic exercise modalities. MET values are drawn from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011) — the gold-standard reference used by exercise physiologists, sports medicine physicians, and clinical dietitians worldwide to quantify exercise intensity and caloric expenditure.
Remedial exercise refers to medically prescribed, structured physical activity designed to address a specific health condition — most commonly obesity, musculoskeletal rehabilitation, cardiovascular deconditioning, or post-surgical recovery. Unlike general fitness programmes, remedial exercise programmes are individually tailored by physiotherapists or clinical exercise specialists, with specific modalities, intensity levels, durations, and progression schedules. This calculator supports the planning, monitoring, and patient education aspects of such programmes.
The MET formula (Calories = MET × Body Weight (kg) × Duration in Hours) is the simplest validated method for estimating gross energy expenditure during exercise. "Gross" means it includes resting metabolic rate — net energy expenditure (the additional burn above resting) would be calculated as (MET − 1) × weight × hours. For clinical purposes, gross expenditure is the standard used in exercise prescription and calorie balance calculations.
Treadmill incline walking has emerged as a particularly effective remedial exercise for obese patients because it achieves high metabolic demand at slow walking speeds. At 40% incline, even slow walking (2–3 km/h) generates a MET of approximately 11–12 — equivalent to vigorous running — while maintaining low impact forces on the knee and hip joints. This makes steep incline walking the preferred cardio modality in patients with obesity-related joint pain or osteoarthritis who cannot tolerate jogging.
For resistance exercises — push-ups, deadlifts, and abdominal crunches — calorie estimates from MET values are conservative, because they do not account for the Excess Post-exercise Oxygen Consumption (EPOC) effect. Resistance training elevates metabolic rate for 12–48 hours after exercise, adding 6–15% additional calorie burn beyond the session itself (Aaberg, NSCA, 2020). This makes resistance exercises particularly valuable additions to obesity management programmes beyond their direct caloric cost.
All calculations run entirely in your browser. No data you enter — body weight, exercise duration, or any other input — is transmitted to any server or stored anywhere. Results can be exported to PDF for clinical records, shared with patients as part of their exercise prescription documentation, or used to track caloric expenditure across sessions over time. The PDF report includes the MET values and formula reference for clinical transparency.

📋 How to Use This Calculator
- 1
Enter your body weight
Input your current body weight in kilograms. The MET formula multiplies directly by body weight — heavier individuals burn more calories for the same exercise duration. Use your measured weight, not an estimate.
- 2
Select your exercise modality
Choose from the dropdown: treadmill walking at various inclines (0%, 10%, 20%, 30%, or 40%), push-ups, deadlifts, or abdominal crunches. Each modality has a validated MET value from the Compendium of Physical Activities.
- 3
Set the exercise duration
Enter the prescribed duration in minutes. For clinical exercise sessions, this is typically 20–60 minutes. You can calculate each exercise separately to build a multi-exercise session total.
- 4
Click Calculate to see calorie burn
The calculator applies the MET formula (Calories = MET × weight × hours) and displays total kcal burned, the MET value used, and the per-minute calorie rate. Results appear instantly.
- 5
Use results to plan your session
Compare different exercise modalities or inclines to understand the caloric impact of each. Use the PDF export to save your exercise prescription with calorie estimates for clinical records or patient education.
🎯 When to Use This Calculator
Clinical weight management
Use to calculate expected calorie expenditure when prescribing structured exercise for obese patients (BMI ≥30). Helps set realistic weekly energy deficit targets alongside dietary intervention.
Treadmill incline prescription
Compare calorie burn across different incline levels to select the optimal therapeutic incline — high caloric expenditure at low walking speed reduces joint impact for obese patients.
Resistance exercise planning
Calculate calories from push-ups, deadlifts, and crunches to combine aerobic and resistance components into a comprehensive remedial exercise programme.
Patient education
Show patients the caloric impact of their prescribed exercises in real numbers — translating "30 minutes on the treadmill at 40% incline" into "920 kcal burned" improves exercise adherence and motivation.
Progress monitoring
Track how calorie burn per session changes as patient weight decreases with successful weight management — adjust exercise duration or intensity to maintain an equivalent energy deficit.
💡 Clinical Pro Tips
MET values are population-derived averages. Obese individuals (BMI ≥35) may expend 10–20% more calories than standard calculations predict during weight-bearing exercises (treadmill, push-ups) because they must move a larger body mass against gravity. The MET formula already accounts for this partially through the weight variable — heavier patients receive proportionally higher calorie estimates.
Treadmill incline at 30–40% is an advanced prescription suitable only for conditioned patients. For newly referred obese patients, begin with 0–10% incline for 15–20 minutes and progress over 4–6 weeks. High incline walking at therapeutic speeds (2–3 km/h) achieves the same energy expenditure as jogging with significantly lower knee joint load — particularly important in patients with obesity-related osteoarthritis.
When combining exercises in a session, calculate each modality separately and sum the totals. A 30-minute treadmill session at 20% incline followed by 3 sets of 15 push-ups and 3 sets of 20 crunches provides a substantially higher caloric deficit than single-modality sessions — and resistance components (deadlifts, push-ups) add post-exercise oxygen consumption (EPOC) that extends calorie burn for 24–48 hours.
For the FITT prescription (Frequency, Intensity, Time, Type), this calculator addresses the Type and Time components. Pair calorie estimates from this tool with heart rate zone targets (use the Heart Rate Zone Calculator) to ensure exercise intensity is in the therapeutic aerobic range (50–70% VO₂max for initial obesity rehabilitation, progressing to 70–80% over time).
