Mistake #1: Starting with Too Much Weight

The Problem: Beginners often start with 40-50 lbs because "it doesn't feel that heavy" standing still. Within 20 minutes, they're struggling. Within 2 miles, they have back pain or blisters.

Why It's Dangerous:

• Causes 40% of beginner rucking injuries
• Leads to poor form (forward lean, rounded shoulders)
• Increases injury risk 3-4x
• Discourages continued training

The Fix:

• Start with 10-15% body weight (20-30 lbs for most people)
• If 180 lbs → start with 20-25 lbs
• If it feels "too easy" for first 2 weeks, that's perfect
• Add 5 lbs every 2-3 weeks maximum

Safe Progression Example:

• Weeks 1-2: 20 lbs
• Weeks 3-4: 25 lbs
• Weeks 5-6: 30 lbs
• Weeks 7-8: 35 lbs

Mistake #2: Poor Posture & Form

The Problem: Forward lean, rounded shoulders, looking down while rucking. This places excessive stress on lower back and reduces breathing efficiency.

Signs of Poor Posture:

• Lower back pain during or after rucks
• Shoulder/neck tension
• Getting winded more easily than expected
• Pack bouncing or swaying

The Fix - Perfect Rucking Form:

• Head: Eyes forward, chin parallel to ground
• Shoulders: Back and down, not hunched forward
• Core: Engaged, slight forward lean from ankles (not waist)
• Back: Straight, natural spine curve maintained
• Arms: Natural swing, 90-degree elbow bend

Quick Form Check: Take photo from side view while rucking. Your torso should be nearly vertical, slight lean from ankles only.

Mistake #3: Rucking Every Day (No Recovery)

The Problem: "More is better" mentality. Rucking 5-7 days per week without rest leads to overuse injuries, chronic fatigue, and burnout.

Warning Signs of Overtraining:

• Persistent soreness that doesn't improve
• Decreased performance (slower pace at same weight)
• Poor sleep quality
• Increased resting heart rate
• Loss of motivation

The Fix:

• Ruck 3-4 times per week maximum
• Take at least 2 full rest days weekly
• Rest days = complete rest or light walking (no weight)
• Muscle grows during recovery, not during workouts

Ideal Weekly Schedule:

• Monday: Ruck
• Tuesday: Rest
• Wednesday: Ruck
• Thursday: Rest
• Friday: Ruck
• Saturday: Long ruck
• Sunday: Rest

Mistake #4: Wrong Footwear

The Problem: Wearing regular running shoes (lack ankle support) or old worn-out shoes. Results in blisters, ankle sprains, and foot pain.

Why Regular Running Shoes Fail:

• Designed for forward motion only (not lateral stability)
• Less durable (wear out faster with extra weight)
• Insufficient ankle support for weighted loads
• Outsole too soft (unstable platform)

The Fix:

• Invest in trail runners (Salomon XA Pro 3D, Merrell Moab 3)
• Or tactical boots (Nike SFB Gen 2) for military prep
• Replace every 300-500 miles of rucking
• Wear moisture-wicking socks (never cotton!)

Mistake #5: Dehydration

The Problem: Not drinking enough water during rucks. Even mild dehydration (2% body weight loss) reduces performance 20% and increases injury risk.

Signs of Dehydration:

• Dark yellow urine
• Headache
• Dizziness or lightheadedness
• Rapid performance decline
• Increased heart rate

The Fix:

• Drink 16-20 oz per hour of rucking
• More in heat (25-30 oz/hour)
• Start hydrated: 16 oz water 30 minutes before ruck
• Continue hydrating after: 20-24 oz within 2 hours post-ruck
• Add electrolytes for rucks over 90 minutes

Mistake #6: Ignoring Pain Signals

The Problem: "Push through the pain" mentality. Confusing good pain (muscle fatigue) with bad pain (injury warning).

Good Pain (OK to Continue):

• Muscle burn/fatigue
• General muscle soreness
• Cardiovascular challenge (breathing hard)

Bad Pain (STOP Immediately):

• Sharp, stabbing pain
• Joint pain (knees, ankles, hips)
• Pain that worsens with each step
• Numbness or tingling
• Pain that persists after stopping

The Fix:

• Stop if experiencing bad pain
• Take 2-3 days off to assess
• If pain persists, see doctor/PT
• Never "push through" joint or sharp pain

Mistake #7: Pack Fit Issues

The Problem: Loose pack that bounces, straps too loose/tight, weight sitting too low. Causes shoulder pain, back strain, and inefficient movement.

The Fix - Proper Pack Adjustment:

• Weight placement: High and close to back (top 1/3 of pack)
• Shoulder straps: Snug but not cutting circulation
• Sternum strap: Fastened, prevents shoulder slippage
• Hip belt: Engaged for 40+ lbs loads
• Test: Pack shouldn't move independently of body

Mistake #8: Neglecting Nutrition

The Problem: Rucking fasted or without proper post-ruck nutrition. Limits recovery and strength gains.

The Fix:

• Pre-ruck (30-60 min before): Light carbs (banana, toast)
• During (90+ minute rucks): Simple carbs (energy gel, dates)
• Post-ruck (within 60 min): Protein + carbs (20-30g protein)
• Daily: 0.8-1g protein per lb body weight

Mistake #9: Increasing Distance AND Weight Simultaneously

The Problem: Adding 5 lbs AND going from 3 to 5 miles in same session. This doubles training stress and injury risk.

The Fix - Progressive Overload Rules:

• Rule 1: Increase distance OR weight, never both
• Rule 2: Add max 10-15% distance per week
• Rule 3: Add max 5 lbs every 2-3 weeks
• Example progression:
• Week 1-2: 3 miles, 25 lbs
• Week 3-4: 3.5 miles, 25 lbs (distance increase)
• Week 5-6: 3.5 miles, 30 lbs (weight increase)

Mistake #10: Skipping Warm-Up & Cool-Down

The Problem: Going straight into heavy rucking without preparation. Increases injury risk, reduces performance.

The Fix:

Proper Warm-Up (5-10 minutes):

• Walk 5 minutes without pack
• Dynamic stretches: leg swings, arm circles, torso twists
• Put on pack, walk 2-3 minutes at easy pace
• Then begin actual ruck

Proper Cool-Down (5-10 minutes):

• Last 5 minutes at reduced pace
• Remove pack
• Walk 3-5 minutes without weight
• Static stretches: quads, hamstrings, calves, hip flexors
• Hydrate and fuel
