1. Six High-Risk Mistakes: Fatal Traps in Movement Details
▶ Mistake 1: Overflexion of the Wrist (Wrist Hyperextension > 15°)
-
Scenario: Wrist bending toward the back of the hand during dumbbell presses or curls.
-
Harm: Carpal Tunnel Syndrome (median nerve compression), Triangular Fibrocartilage Complex (TFCC) injury.
-
Correction:
✅ Neutral Grip: Align the palm with the forearm (imagine "holding a water cup").
✅ Slight Rotation Adjustment: Palms face forward during presses (ulnar slight internal rotation); palms face upward during curls (radial neutral position). -
Tools: Use wrist-wrapped training gloves (e.g., PowerLifting style) or place a towel roll (2-3cm thick) under the wrist.
▶ Mistake 2: Lower Back Arching (Lumbar Hyperlordosis > Physiological Curvature)
-
Scenario: Lower back collapsing or over-arching during deadlifts or squats.
-
Harm: Lumbar Disc Herniation (L4-L5 most vulnerable), Erector Spinae Strain.
-
Correction:
✅ Core Activation: Imagine "pulling the navel toward the spine" (activate transverse abdominis), lower ribs downward (avoid shrugging).
✅ Visual Check: Side-view alignment – earlobe, acromion, greater trochanter, lateral knee, and lateral ankle should form a straight line. -
Alternative Training: Kneeling Deadlift → Romanian Deadlift → Traditional Deadlift (progressive advancement).
▶ Mistake 3: Blind Pursuit of Heavy Weights (Ignoring RPE Self-Monitoring)
-
Data: 62% of injuries among beginners are caused by overload (Journal of Sports Medicine, 2024).
-
Solutions:
✅ RPE 6-7 Principle: The last 2 reps of each set should be controlled (not to failure). Example: 10kg deadlift for 8 reps with RPE=6 (10 being maximum effort).
✅ Weight Pyramid: Start light → heavy → light (e.g., 2kg→3kg→2kg); avoid starting with maximum weight. -
Case Study: Begin shoulder presses with 1kg, increase by 0.5kg every 2 weeks; reduce by 1kg if form deteriorates.
▶ Mistake 4: Knee Valgus Collapse
-
Biomechanics: Weak gluteus medius → femoral internal rotation → concentrated knee pressure (MCL + meniscus injury).
-
Correction:
✅ Activate Gluteus Medius: Side-lying leg lifts (1-2kg weight), 3 sets ×15 reps/side.
✅ Form Adjustment: Align knees with second toes during squats (use resistance bands around knees). -
Warning Signs: Knee pain during stairs, post-squat swelling (stop training immediately).
▶ Mistake 5: Disordered Breathing Patterns (Breath-Holding/Thoracic Breathing)
-
Science: Valsalva maneuver increases intracranial pressure (suitable for heavy lifts >85% 1RM). Daily training should use "nose-in, mouth-out" breathing.
-
Proper Technique:
✅ Eccentric Phase (e.g., squatting): Inhale slowly through the nose for 4 seconds (diaphragm descends).
✅ Concentric Phase (e.g., standing): Exhale through the mouth for 2 seconds (core engaged). -
Tools: Use a breathing metronome (4-2 rhythm) or pair "abdomen contraction-exhalation" drills.
▶ Mistake 6: Incorrect Movement Paths (Joint Trajectory Deviation)
-
Examples:
❌ Locked elbows during dumbbell flyes (increased shoulder stress).
❌ Leaning backward during bicep curls (momentum cheating). -
Correction:
✅ Mirror Training: Record videos to compare with standard paths (e.g., vertical dumbbell path during presses: ear→shoulder→chest).
✅ Range Limitation: Keep elbows slightly bent at 150° during flyes (use resistance bands); press back against a wall during curls.
2. Injury Emergency Management: Full-Cycle Care from Warning to Recovery
▶ Rotator Cuff Injury
-
Warning Signs:
✓ Night shoulder pain (especially when side-sleeping).
✓ Pain during shoulder abduction (60-120°, "painful arc" sign).
✓ Weakness (e.g., inability to perform 1kg lateral raises). -
Acute Phase (72 hours):
RICE Principle: Rest → Ice (15 mins/session, 2-hour intervals) → Compression → Elevation. -
Rehab (Post 7 days):
✅ Band External Rotations (2-3kg resistance), 3 sets ×15 reps/side.
✅ Scapular Retractions (1kg weight), 3 sets ×20 reps.
▶ Lower Back Discomfort (Lumbar Strain)
-
Immediate Relief:
i. Cat-Cow Stretch: Kneeling with 1kg weight; inhale (arch back), exhale (round spine), 10 reps.
ii. Child’s Pose Stretch: Hips to heels, arms extended with 1kg weight, forehead on floor, hold 30s. -
Prevention:
✅ Dead Bug (1kg weight), 3 sets ×12 reps/side.
✅ Bird-Dog (2kg weight), 3 sets ×10 reps/side.
▶ Elbow Tendonitis (Tennis Elbow)
-
Causes: Excessive flexion/extension (e.g., >3 sets/day of bicep curls).
-
Treatment:
✓ Stop forearm rotation movements (e.g., hammer curls) for 2 weeks.
✓ Eccentric Training: Single-arm dumbbell extensions (3kg), slow lowering (4s), 3 sets ×8 reps.
✓ Physical Therapy: Foam roll forearm extensors (2x daily).
3. Protective Gear Guide: Scientific Support, Not Over-Reliance
| Gear Type | Applicable Scenarios | Selection Criteria | Contraindications |
|---|---|---|---|
| Wrist Wraps | Pressing movements (bench press) | Breathable elastic material, >180° wrist coverage (e.g., Mueller Wrist Wraps) | Daily curls (unnecessary) |
| Belt | Heavy deadlifts/squats (>80% 1RM) | 4-6cm wide steel-reinforced (e.g., Rogue Leather Belt) | Core training (limits activation) |
| Knee Sleeves | Knee injuries/heavy leg training | Hinged support (e.g., Bauerfeind Genutrain) | Light squats (no prior injury) |
| Gloves | Dumbbell grip (sweaty hands) | Half-finger anti-slip (preserve dexterity) | Precision moves (e.g., flyes) |
Usage Principles:
-
Preventive Use: Only for new movements/heavy lifts (e.g., first 10kg deadlift).
-
Phased Removal: Gradually reduce reliance after 4 weeks of stable form.
-
Biomechanical Fit: Wraps cover ulnar styloid; belts align with lumbar curve (15° forward tilt).
4. Phased Prevention Strategy: Safety Progression from Beginner to Advanced
▶ Beginner Phase (1-4 Weeks)
-
Focus: Build movement patterns, enhance joint awareness.
-
Actions:
✓ Use 1-2kg dumbbells for basics (squats, presses).
✓ Post-set "Joint Check": Wrist/shoulder/back pain? Adjust immediately.
▶ Intermediate Phase (5-12 Weeks)
-
Focus: Increase complexity, prevent overuse injuries.
-
Actions:
✓ Introduce supersets (e.g., squat + press), rest 90s between sets.
✓ Weekly "Movement Screening": FMS test (check squat symmetry, shoulder mobility).
▶ Advanced Phase (12+ Weeks)
-
Focus: Break plateaus, strengthen joint stability.
-
Actions:
✓ Add unstable training (e.g., balance pad dumbbell rows).
✓ Bi-monthly musculoskeletal ultrasound (focus: rotator cuff, quadriceps tendons).
5. Special Populations: Customized Risk Control
▶ Menstruating Women
-
Avoid: Intra-abdominal pressure-increasing moves (weighted crunches, handstands).
-
Alternatives: Seated dumbbell presses (1-2kg) → reduce edema; side-lying leg lifts (unweighted).
▶ Postpartum Mothers (Diastasis Recti >2 Fingers)
-
Avoid: Planks, Russian twists.
-
Safe Moves: Kneeling dumbbell flyes (1kg) → strengthen pecs; Dead Bug (1kg) → activate deep core.
▶ Osteoporosis Risk (Age 45+)
-
Weight Limits: Lower body ≤10kg (avoid spinal compression); upper body ≤5kg.
-
Optimal Moves: Standing dumbbell presses; Romanian deadlifts (protect lumbar spine).
