What is an Army Ranger Ruck?
The Army Ranger ruck march is legendary for its difficulty, demanding pace, and strict standards. For years, aspiring Army Rangers have trained for ruck marches by carrying 40 to 65 pounds for long distances—often over rough, steep terrain—at a fast 15-minute-per-mile pace. But you don’t have to be in the military to learn from the Ranger approach. As a certified personal trainer who lost 90 lbs through rucking, I, Preston Shamblen, draw heavily from the Ranger template for both clients and my own training.
How to Train Like an Army Ranger
- Proper Load: Start light (20-30 lbs), but work up to 45+ lbs if your body allows and your goals include high-intensity endurance. Always ensure your total weight (pack plus supplies) matches your ability and goal.
- Pace and Time: Ranger rucks are fast—aim for 15-16 min/mile over 6+ miles. Start slow and build up. Focus on maintaining pace, resting only at planned intervals.
- Terrain: Get outside and seek trails, hilly parks, or dirt roads. The more unpredictable, the better the carryover for Ranger-style toughness.
- Graduated Stress: Add weight or distance in small steps (5–10% at a time) to reduce risk of injury and keep progressing.
The Right Gear for a Ranger Ruck
Load balance and durability are critical in a heavy ruck setup. While I love a good weighted vest for many rucks, serious Ranger-style training goes smoother with purpose-built packs.
- The GORUCK Rucker 4.0 20L is ideal for Army Ranger-style loads. It’s built to handle abuse, fits weight plates securely, and won’t destroy your shoulders or low back.
- For actual weight, consider the Yes4All Ruck Weight Plate for its easy grip and plate compatibility.
Staying Safe and Hydrated
Long, fast rucks can wreck your hydration and electrolyte balance. I always keep water close, choose a route with refill options, and—for extra tough sessions—mix up a hydration supplement. Pump-Ocalypse pre-workout (with glycerol) is my personal go-to for hydration and endurance on longer rucks or hot days.
Tracking Your Ruck Calories
If you want Army Ranger ruck results, tracking your calorie burn is a must—especially if fat loss or fitness conditioning is your goal. Use tools to estimate your burn accurately and plan your fueling. I recommend the Rucking Calorie Calculator here:
Final Thoughts from Preston Shamblen
Even after my transformation and becoming a certified personal trainer, I keep the Army Ranger ruck approach in my training playbook. It’s hard, but it’s reliable—and it teaches discipline, grit, and self-awareness. Take it slow, listen to your body, and upgrade your gear as you progress. Happy rucking!
