How Many Calories Do Planks Burn? Plank Calories Burned Explained
You’re adding planks to your workout and wondering: how many calories do planks burn, really? The honest answer is probably less than you’d hoped — but the real value of planks isn’t calorie burn anyway. Plank calories burned per minute are modest compared to cardiovascular exercise, but the exercise’s ability to build core endurance and stability makes it highly complementary to workouts that do burn significant calories. Understanding calories burned planking helps you set realistic expectations, while knowing the actual plank calories per hour helps you account for them accurately in your training log.
This guide gives you the numbers on calories burned plank by duration and body weight, and explains where plank exercise fits in a calorie-burning program.
How Many Calories Do Planks Burn Per Minute
A plank is a low-intensity isometric exercise, typically performed at around 3–4 METs (metabolic equivalents). Compare this to running at 6 mph (about 10 METs) or cycling at moderate effort (7–8 METs). For a 150-lb (68 kg) person:
- Plank at 3.5 METs: (3.5 x 68 x duration in hours) = approximately 4 calories per minute
- Same person at rest (1.0 MET): approximately 1 calorie per minute
- Net additional calories from planking: about 3 calories per minute over baseline
For a 180-lb (82 kg) person, plank calories burned per minute rises to about 4.5–5 kcal. Heavier individuals always burn more calories for the same exercise because more mass requires more energy to hold in position.
Calories Burned Planking for Common Durations
Using the MET formula for a 155-lb (70 kg) person at 3.5 METs:
- 1 minute plank: ~4 calories
- 5 minutes total (multiple sets): ~20 calories
- 10 minutes total: ~41 calories
- 30 minutes (sustained or accumulated): ~123 calories
Most workout routines include 3–5 minutes of total plank time across sets. At that volume, plank calories contribute about 12–20 kcal to a workout — meaningful but not the primary calorie burner in a session.
Why Planks Are Still Worth Doing
Calories burned plank-style are low because planks are isometric — the muscles contract without moving. The real benefit is core stability development: the transversus abdominis, multifidus, and deep spinal muscles all strengthen through plank work in a way that directly improves performance in squats, deadlifts, and overhead pressing. Stronger core muscles allow heavier loading in compound movements, which burns far more calories than the plank itself.
Planks also improve posture, which increases NEAT (non-exercise activity thermogenesis) by keeping you in better alignment throughout the day — a subtle but real calorie effect over time.
How to Maximize Calories Burned in a Plank
If calorie burning from planking is a goal, these variations increase intensity:
- Plank shoulder taps: Alternately touching each shoulder while in plank position adds a dynamic component, raising calorie burn by 20–30% per minute.
- Plank to push-up: Moving from forearm plank to full plank position continuously combines isometric and dynamic work.
- Side plank rotations: Adds rotational muscle engagement to the static hold.
Extending plank duration also helps: a 60-second plank burns about three times more than a 20-second plank, and the technique practice from longer holds improves form quality in all core exercises.
Next steps: Use planks as a core stability tool rather than a calorie-burning exercise. Track your maximum unbroken plank time every two weeks as a fitness metric. Pair plank work with 20–30 minutes of zone 2 cardio for a session that builds core endurance while also generating meaningful calorie burn.
