What is rucking?

Rucking is loaded walking: you carry a weighted backpack, or rucksack, at a brisk pace. It comes from military training, where ruck marching builds the endurance to move a heavy load over distance. Today it’s one of the simplest ways to add strength training to the walking you already do.

Compared with unloaded walking, the extra weight raises your heart rate and calorie burn and works your legs, core and postural muscles, with far less impact than running.

How to start rucking

Four rules for your first month.

Start light

Carry about 10% of your body weight. Add load only after your body adapts.

Keep it short

One to two miles, two or three times a week. Build distance before weight.

Use proper form

Stand tall, keep the load high and tight, and hold a pace you can talk at.

Look after your feet

Proper footwear and merino socks prevent most beginner blisters.

Yes, for light loads. Once you add ruck plates, a dedicated rucking backpack holds the weight higher and saves your shoulders.

It’s lower impact and builds more strength; running builds more speed. Many people do both.

A vest spreads the load around your torso for workouts; a backpack is better for long walks.
