5 Key Concepts
Rucking
Carrying weight in a backpack while walking. It is the foundation of Special Forces training, serving as a comprehensive test of physical endurance and mental fortitude, and is now promoted for general fitness and well-being.
Green Berets' Mission
Army Special Forces (Green Berets) primarily work 'by, with, and through' local partner forces in other countries. They act as diplomats and trainers, aiming to achieve strategic objectives with a minimal U.S. footprint, as exemplified in Afghanistan post-9/11.
Special Forces Selection (SFAS)
A three-week individual assessment process where candidates undergo continuous land navigation, physical tests, and mental stressors. It's designed to test autonomy, resilience, and the ability to perform under extreme duress, with a high self-selection attrition rate.
Go Bag
A bag of essential supplies, such as ammunition, water, radios, and medical gear, kept ready for immediate use in emergencies. In a civilian context, it's prepared for natural disasters or situations requiring rapid evacuation.
Rucking Offset/Heel Lift
Refers to the heel-to-toe drop in footwear. An 8-millimeter drop, for instance, is recommended to alleviate strain on the Achilles tendon and prevent shin splints, especially when carrying significant weight over long distances.

While physical fitness is a prerequisite, mental toughness, the ability to perform under extreme stress, and an unwavering will to not quit are the primary predictors, often surprising those who appear physically strongest.
You can start with any backpack you have, putting 10-20 pounds of weight (e.g., rice, water, rocks) in it. A dedicated rucksack offers better comfort, stability, and durability for heavier loads and longer distances.
Weight vests are crucial for soldiers/police for protection, but rucksacks generally promote better posture by allowing shoulders to roll back and facilitating deeper breathing. Rucksacks are often more comfortable for general rucking activities.
Start simply with a modest weight (e.g., 20 pounds) for a couple of miles, a few times a week. Listen to your body, and gradually increase weight or distance as your comfort and strength improve.
Most injuries, such as shin splints or Achilles pain, arise from starting too fast, too soon, with too much weight. To avoid them, reduce weight and distance, listen to your body, and ensure you have supportive footwear.
Rucking is extremely healthy for physical and mental well-being, improving strength, VO2 max, and sleep quality. It also fosters community, purpose, and confidence by engaging in challenging physical activity.
Rucking on a treadmill is acceptable for its physiological benefits, safety, and practicality, especially for those with time constraints or specific needs. However, it misses the additional benefits of being outdoors, such as sunshine, wind, and varied terrain.
Training plans typically involve building up mileage, aiming to complete at least a marathon-distance ruck. One effective strategy is to train with heavier weight (e.g., 50-60 pounds) at a consistent pace, rather than always training at the event's lighter weight.
22 Actionable Insights
1. Avoid Future Regret
Listen to your inner voice about what you know you need to do, as prioritizing safety or delaying action often leads to regret later in life. Don’t let the desire for safety prevent you from pursuing what is right for your personal path.
2. Seek Help, Build Community
Recognize that asking for help is a strength, especially when struggling, and actively seek to be part of something bigger than yourself. Foster deep, lasting friendships through shared hard experiences, as social health is vital.
3. Cultivate Compassion & Kindness
Practice kindness and compassion in your interactions, as you never know what unseen struggles others are facing. This understanding can make you more empathetic and improve your relationships.
4. Embrace Life’s Hard Lessons
Actively push on life and engage with its challenges to learn what truly matters to you, what you will and won’t do, and why. These difficult experiences are crucial for personal growth and self-discovery.
5. Focus on Controllable Efforts
Set yourself up for optimal physical and mental response by dedicating effort to the variables you can control, rather than worrying about unknowable outcomes or external challenges. This approach maximizes your preparedness and reduces anxiety.
6. Prepare Thoroughly for Confidence
Prepare thoroughly for any endeavor to build confidence and avoid self-doubt, as cutting corners will lead to a ‘what if’ game that undermines performance when challenges arise. Show up ready, and trust the outcome.
7. Start Rucking Immediately
Begin rucking today with any backpack and household items (like bags of rice or water) cinched tight, rather than waiting to purchase specialized gear. This overcomes procrastination and allows you to immediately start being active.
8. Beginner Rucking Protocol
Start rucking with a modest weight (e.g., 20 lbs) for a couple of miles a few times a week, expecting initial shoulder soreness as muscles strengthen. Gradually increase weight or distance as you become more comfortable and fit.
9. Optimize Body for Rucking
Aim for a lean, strong physique rather than excessive bulk, as non-functional body weight increases the load carried with every step, making you slower and less efficient for rucking. You can never be too strong, but you can be too big.
10. Harden Feet for Rucking
Practice proper foot care by starting with thin socks and immediately addressing any hotspots by wringing out or changing socks. This prevents blisters and promotes calluses, which are crucial for long-distance rucking performance.
11. Choose Rucksack Over Vest
Opt for a rucksack instead of a weight vest for rucking to promote better posture and breathing, as weight vests can lead to a hunched posture and restrict deep breaths. A rucksack can help roll your shoulders back, maintaining solid posture.
12. Experiment with Ruck Straps
Adjust or experiment with chest straps and hip belts, prioritizing a stable, high, and tight load on your back, as personal preference and load weight dictate comfort and efficient blood flow. The goal is always stability to prevent injury.
13. Wear Supportive Rucking Footwear
Use supportive footwear with an appropriate heel drop (e.g., 8mm) for rucking, especially with heavier loads or on uneven terrain, to prevent injuries like shin splints and protect the Achilles. Avoid minimalist shoes for rucking, as they lack necessary support.
14. Maintain Good Rucking Form
Avoid leaning forward or excessive hip pivoting when rucking, focusing on mastering the movement with appropriate weight before increasing load or distance. This prevents injury and ensures proper muscle engagement, similar to mastering perfect pushups.
15. Prevent Rucking Injuries
Prevent rucking injuries by starting slowly, using modest weight (20-30 lbs), listening to your body, and reducing weight/distance if pain (like shin splints or Achilles pain) occurs. Avoid running with weight unless highly conditioned, opting for a shuffle to increase intensity safely.
16. Incorporate Hill Rucking
Include rucking up steep hills to boost VO2 max and ruck down steep hills slowly with weight to train eccentric strength. This is crucial for maintaining your body’s ‘brakes’ that naturally decline with age.
17. Vary Rucking Workouts
Adjust weight and speed (lighter/faster, heavier/slower, or moderate) in your rucking workouts to target different physiological systems and adapt to your comfort level. This flexibility allows for diverse and effective training.
18. Prepare a Disaster Go Bag
Assemble a ‘go bag’ containing essential medical supplies and weapons for preparedness in case of natural disasters or societal breakdowns. Recognize that such events can quickly lead to lawlessness and self-reliance is critical.
19. Ruck Instead of Roll When Traveling
Use a rucksack instead of roll bags when traveling, especially in airports or places with uneven terrain like cobblestone roads. This maintains hands-free movement, builds fitness, and enhances your overall travel experience.
20. Travel with Improvised Weights
If you can’t bring ruck plates, use alternative weights like rocks, wrapped dumbbells from hotel gyms, or a stuff sack with dirty clothes when traveling. This allows you to maintain your rucking routine even without specialized gear.
21. Train for Extreme Rucks
For extreme rucking events (e.g., 80K), train by rucking at least marathon distances, often with heavier weights (50-60 lbs) than the event itself, to maintain speed and build endurance. Gradually increase your mileage and load.
22. Define ‘Marginal Decade’ Goals
Set specific, quantifiable physical goals for your ‘marginal decade’ (e.g., rucking 3 miles with 20 lbs over uneven terrain) to provide clear targets for your current fitness and longevity efforts. This helps maintain motivation and purpose.

Preparing Feet for Rucking
Jason McCarthy- Start out with thin socks.
- If any hotspots develop, wring out or change those socks.
- Continue rucking to allow hotspots to eventually turn into calluses, which provide protection against blisters.
