Why Rucking is the Ultimate Workout
Lifting weights gets you strong. Running gets you fit. Rucking does both at the exact same time. By strapping weight to your back and walking out the front door, you engage your shoulders, core, glutes, and legs in a prolonged, calorie-torching endurance session.
The Science of Working Under Load
When you walk without a pack, your body has evolved to be incredibly efficient, burning minimal energy. As soon as you add a heavy load, that efficiency breaks down. You must recruit far more muscle fibres just to stabilize your spine and take a single step.
Research shows that on average, a 15kg to 20kg pack can increase your base walking calorie burn by 30% to 50%. For bigger guys carrying military-grade loads (30kg+), the caloric demands rival those of high-intensity long-distance running.
How to Start Rucking Safely
- The Gear: You don't need a fancy military rucksack to start. Any sturdy old backpack will do. For weight, wrap some dumbbells or old textbooks in a towel (so they don't dig into your back) and drop them in.
- Start Light: Ego is the enemy. Start with 5kg or 10kg. Let your shoulders, traps, and lower back adapt to carrying the load over distance. Increase the weight by 2.5kg every week or two.
- Keep it High and Tight: The number one mistake beginners make is letting the backpack hang low near their bum. Pull the shoulder straps extremely tight so the weight sits high up between your shoulder blades. Your lower back will thank you.
