Why It Works

The Science Behind Adding Weight

Rucking activates your posterior chain, elevates heart rate into the aerobic zone, and builds postural endurance — all without the joint stress of running.

🔥

Calorie Burn

Carrying 20% bodyweight increases caloric expenditure by 30–40% versus unloaded walking at the same pace.

💪

Functional Strength

Loaded carries build real-world strength in glutes, hamstrings, and spinal erectors.

🦴

Joint-Friendly

Low impact. High reward. Rucking stresses your bones just enough to promote density without the knee wear of running.

🧠

Mental Edge

Time outdoors under load builds grit — the same method used by special operations forces worldwide.

Common Questions

FAQ

Is rucking better than running? +

Rucking is lower impact and builds functional strength while torching serious calories. Many athletes ruck on off days from running.

How much weight for a beginner? +

Start at 10–20 lb, roughly 10% of your bodyweight. Build gradually — add weight or distance, never both at once.

Vest or backpack first? +

Vest for home workouts and running. Backpack for long walks and hikes. On a budget, a vest delivers more versatility per dollar.

What supplements help with rucking? +

Creatine supports ATP resynthesis. BCAAs reduce muscle breakdown. Electrolytes on rucks over 45 minutes. Vitasonic Labs carries all three.

Can I ruck every day? +

Light rucking can be done daily. Heavy rucking needs recovery time. Start 3x per week and add days as your body adapts.

Is the ERIC FLAG vest worth the price? +

Yes — the 0–40 lb range means it scales with you for years. Cheaper vests top out at 30 lb and you'll outgrow them.
