Exercise: Standard Wall Sit
Isometric lower-body hold targeting quadriceps, glutes, and calves under sustained tension
This is approximately 0.205% of a 2000 kcal daily diet.
Isometric advantage: Wall sits build significant quadriceps endurance with very low joint stress — making them ideal for rehab, skiing fitness, and injury prevention.
Note: Wall sits are a low-calorie exercise. Their primary value is building isometric quad strength and endurance, not calorie expenditure. Accuracy: ±25–35%.

Wall sits are a common exercise for cyclists and triathletes to build quad endurance. I built this calculator to help athletes understand the true calorie cost and training value of this underrated isometric exercise.
How Wall Sit Calories Are Calculated
A wall sit is an isometric (static) lower-body exercise performed by holding a seated position with your back flat against a wall and knees bent at approximately 90°. Unlike dynamic exercises, there is no movement — the muscles sustain continuous tension throughout the hold.
This calculator uses the MET-based calorie formula from the Compendium of Physical Activities. MET (Metabolic Equivalent of Task) measures how much energy an activity requires relative to rest (1 MET ≈ 1 kcal per kg of body weight per hour).
The Wall Sit Calorie Formula
Calories = MET × Weight (kg) × Time (hours)
Wall sits are timed in seconds or minutes, so the duration is converted to hours before applying the formula:
Time (hours) = Duration (seconds) ÷ 3600
MET Values by Wall Sit Variation
| Variation | MET Value | Description |
|---|---|---|
| Standard Wall Sit | 3.5 | Both legs at 90°, back flat against wall |
| Single-Leg Wall Sit | 4.5 | One leg extended, doubled quad demand per leg |
| Weighted Wall Sit | 5.0 | Plate, dumbbell, or weight vest on thighs |
MET values for wall sits are derived from isometric exercise classifications in the Compendium, analogous to other sustained static lower-body holds. The isometric nature means energy expenditure is lower than equivalent dynamic exercises despite the significant perceived effort.
Calories Burned by Duration and Body Weight (Standard Wall Sit, MET 3.5)
| Duration | 60 kg (132 lbs) | 70 kg (154 lbs) | 80 kg (176 lbs) | 90 kg (198 lbs) |
|---|---|---|---|---|
| 30 seconds | 1.0 | 1.2 | 1.4 | 1.6 |
| 1 minute | 2.1 | 2.4 | 2.8 | 3.2 |
| 2 minutes | 4.2 | 4.9 | 5.6 | 6.3 |
| 5 minutes | 10.5 | 12.3 | 14.0 | 15.8 |
| 10 minutes | 21.0 | 24.5 | 28.0 | 31.5 |
Why Isometric Exercises Burn Fewer Calories Than Dynamic Ones
In dynamic exercises (squats, lunges, box jumps), muscles repeatedly contract and relax, driving repeated ATP synthesis and high oxygen consumption. In isometric exercises like wall sits:
- No concentric work: Muscles maintain constant length — no movement means no repeated contraction cycles
- Lower ATP turnover: Sustained tension uses energy more efficiently than repeated contractions
- Occlusion effect: At high levels of contraction, blood flow is partially restricted, which limits oxygen delivery — the body shifts toward anaerobic pathways
However, the perceived effort in a wall sit is typically much higher than the calorie burn suggests. A 2-minute wall sit that burns ~5 kcal feels significantly harder than 5 kcal worth of walking.
Example Calculation
A 75 kg (165 lbs) person holds a 90-second standard wall sit:
- MET = 3.5
- Weight = 75 kg
- Time = 90 ÷ 3600 = 0.025 hours
- Calories = 3.5 × 75 × 0.025 = 6.6 kcal
Important Disclaimer
Calorie estimates carry a margin of error of approximately ±25–35%. Wall sits are primarily valued for quadriceps strength and endurance development, not calorie burn. For fat loss, pair wall sit training with higher-intensity cardio in a combined programme. These calculations cover sustained hold time only — brief rests between sets are not included.
Frequently Asked Questions
A 1-minute standard wall sit burns approximately 2.1–3.2 calories depending on body weight. A 60 kg person burns about 2.1 calories; a 70 kg person burns about 2.5 calories; an 80 kg person burns about 2.8 calories; a 90 kg person burns about 3.2 calories. Single-leg wall sits burn approximately 30% more per minute.
Wall sits do not specifically target belly fat — spot reduction is not supported by scientific evidence. Wall sits burn a modest number of calories and build quadriceps, glute, and calf endurance. For effective fat loss, combine wall sit training with higher-intensity cardio exercises and a caloric deficit.
Standard wall sits have a MET value of approximately 3.5 from isometric exercise classifications in the Compendium of Physical Activities. Single-leg wall sits have a higher MET of around 4.5 due to the doubled load per leg. Weighted wall sits reach MET 5.0 with added resistance.
A 5-minute standard wall sit burns approximately 10.5–15.8 calories depending on body weight. A 60 kg person burns about 10.5 calories; a 70 kg person burns about 12.3 calories; an 80 kg person burns about 14 calories; a 90 kg person burns about 15.8 calories.
Wall sits burn few calories directly (MET 3.5) and are not an efficient weight loss exercise on their own. However, they build significant quadriceps and glute muscle mass over time, which raises resting metabolic rate. They are best used for strength and endurance development rather than calorie burning.
For strength and endurance gains, aim for 3 sets of 30–60 seconds as a beginner, progressing to 3 sets of 90–120 seconds as you improve. Elite athletes can hold for 5+ minutes. Hold until failure (while maintaining good form) is also an effective approach for progressive overload. See our guide on how long to hold a wall sit for more detail.
