Key Takeaways
- A walking lunge burns approximately 0.2-0.5 kcal per rep depending on body weight and pace.[1]
- Jump lunges (8.0 MET) burn roughly double the calories of stationary lunges (3.5 MET) per rep.[3]
- Barbell-weighted lunges (5.5 MET) add about 57% more energy demand than bodyweight stationary lunges.[4]
- Rest periods between sets still contribute some calories at resting metabolic rate (1.0 MET).
- These are informational estimates for personal journaling. Individual results vary with form and depth.

Per-Rep Calories by Pace (40 walking lunges)
| Pace | 55 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|
| Slow (8 rpm) | 0.481 | 0.613 | 0.744 | 0.875 |
| Moderate (12 rpm) | 0.321 | 0.408 | 0.496 | 0.583 |
| Fast (16 rpm) | 0.241 | 0.306 | 0.372 | 0.438 |
| Very Fast (20 rpm) | 0.193 | 0.245 | 0.298 | 0.350 |
How the Estimate Works
The calculator uses the MET formula with separate work and rest phases:[1]
Work Calories = (MET × 3.5 × Wt_kg × Work_min) ÷ 200
Rest Calories = (1.0 × 3.5 × Wt_kg × Rest_min) ÷ 200
Total = Work Calories + Rest Calories
Work duration is derived from total reps divided by pace (reps per minute). In set-rep mode, rest duration equals (sets - 1) × rest seconds between sets.
Lunge Variations Explained
Stationary & Reverse (3.5 MET)
In-place lunges with alternating legs. Reverse lunges step backward, reducing knee shear forces. Both have similar energy demands.[2]
Walking & Lateral (4.0 MET)
Walking lunges add forward locomotion. Lateral lunges step sideways, targeting the inner thighs and hip abductors.[3]
Jump Lunge (8.0 MET)
Explosive alternating jump lunges. The plyometric component dramatically increases energy cost, making it the highest-calorie lunge variation.[6]
Weighted: Dumbbell & Barbell (5.0-5.5 MET)
Added resistance increases muscle demand. Barbell lunges (front or back rack) rate slightly higher than dumbbell due to core stabilization.[4]
Bulgarian Split Squat (5.0 MET)
Rear foot elevated on a bench. Increased single-leg range of motion and balance demand compared to standard lunges.[5]
Curtsy Lunge (3.8 MET)
Cross-behind stepping pattern that emphasizes the gluteus medius. Similar energy cost to standard lunges with different muscle emphasis.[7]
Walking vs Stationary Lunges
Walking lunges (4.0 MET) burn approximately 14% more calories than stationary lunges (3.5 MET) per rep due to the added forward locomotion component:[3]
- Walking: Requires propulsive force to move forward plus deceleration at each step. Engages hip flexors more actively.
- Stationary: No locomotion cost. Easier to control depth and form. Better for beginners or limited space.
- Reverse: Steps backward, similar MET to stationary. Often preferred for reduced anterior knee loading.
For calorie purposes, the difference is modest. The choice between variations should prioritize form and comfort.
Body Weight Factor
Body weight has a direct linear effect on lunge calorie estimates. A 100 kg person burns approximately 43% more per rep than a 70 kg person doing the same variation at the same pace.[7]
Lunges involve moving the full body mass through a deep squat pattern, making body weight the primary driver of energy expenditure per repetition.
