Introduction to Weight Loss with Rucking

By Rucking Calculator Team 2025-01-04

The “Cheat Code” for Calorie Burn

Weight loss is math. Calories in < Calories out. The problem with “Calories out” is that most high-burn exercises (running, HIIT, CrossFit) are hard to sustain daily. They hurt your joints, and they are mentally exhausting.

Rucking is different.

It turns a standard walk into a fat-burning workout.

Comparisons (1 Hour for 180lb Male)

ActivityCalories BurnedImpact Level
Walking (3mph)~250Low
Rucking (20lbs, 3mph)~400-450Low-Moderate
Running (5mph)~600High

Rucking bridges the gap. You get nearly the burn of a slow jog, but you can do it while listening to a podcast, walking the dog, or commuting.

Why it Targets Fat

Rucking keeps you in “Zone 2” heart rate (60-70% of max). This is the famous “Fat Burning Zone”. High-intensity cardio often burns glycogen (muscle sugar). Zone 2 primarily burns fat stores for fuel.

Because it is lower stress, you can do it every single day. Consistency beats intensity every time.

A Simple Plan

  1. Week 1: 3 walks, 20 mins, 10 lbs.
  2. Week 2: 3 walks, 30 mins, 15 lbs.
  3. Week 3: 4 walks, 40 mins, 20 lbs.

By Week 3, you are burning an extra 1000+ calories a week just by carrying a backpack. That is 1.5 lbs of fat loss a month without changing your diet.
