Frequently Asked Questions
How many calories does rucking burn per hour?
Rucking burns between 400 and 700 calories per hour depending on body weight, rucksack load (usually 10% to 30% of body weight), terrain incline, and walking speed (2.5 to 4.0 mph).
Does adding 20 lbs to a rucksack burn significantly more calories?
Yes! Carrying a 20 lb rucksack increases energy expenditure by approximately 20% to 35% compared to unweighted walking, as your leg and core muscles work harder to stabilize the added mass.
What is the formula for calculating rucking calories?
Rucking uses the Pandolf load-carriage equation: Calories = MET × Weight (kg) × Duration (hours). Unweighted walking at 3 mph is 3.5 METs, while rucking with 30 lbs on steep terrain reaches 7.0–9.0 METs.
