Backward Cross / Backward Cross Pull
SLALOM OS V4.2 "MENTOR" CORE TEMPLATE ANALYSIS
Move: Backward Cross (Backward Cross Pull)
Classification: C-TIER (Foundational Precision)
Rationale: This move is the foundational building block for all backward complex moves. It requires consistent multi-plane control (transitioning from an outside to an inside edge), moderate neural sync for rhythmic timing, and has a medium fragility risk if balance is lost during the cross. It is essential for scoring in novice and intermediate competition categories.
0. PREREQUISITES (NON-NEGOTIABLE)
System-Check: Auto-Populated from C-Tier Requirements: Confident backward skating, backward gliding on each foot (>3 seconds), and mastery of backward crossovers (a D-Tier skill) for momentum generation.
Physical Attributes: Adequate hip external rotation and abduction mobility to cross the legs. Strong gluteus medius for pelvic stability during the weight transfer.
Safety Mandates: Knee pads and wrist guards are mandatory during learning. Must be practiced on a smooth, flat surface with consistent traction.
1. MOVE DEFINITION
Name: Backward Cross (Backward Cross Pull)
Biomechanical Key: The powerful engagement of the supporting hip and glute to "pull" the body over the skating foot, which is actively gripping an inside edge, allowing the free foot to cross underneath and behind with control.
2. TECHNICAL EXECUTION
Phase 1 (The Setup & Glide): Generate moderate backward speed using crossovers. Glide backward on one foot (e.g., left foot), maintaining a deep knee bend and stable upper body.
Phase 2 (The Edge Set & Pull): Firmly set your skating foot (left) on a strong inside edge. Engage your left hip to initiate a powerful "pull" motion, drawing your body laterally to the right.
Phase 3 (The Cross): As your body moves sideways, smoothly cross your free foot (right) underneath and behind your skating ankle. Your weight begins to transfer to the crossed (right) foot.
Phase 4 (The Transfer & Reset): Complete the weight transfer onto the new skating foot (right), which now grips its own inside edge. The former skating foot (left) is lifted and prepared to be set down for the next cross or to continue gliding.

3. DYNAMIC GEAR IMPACT ANALYSIS
Gear Database Query:
INPUT YOUR SETUP: [Boot Model: ____], [Frame: ____], [Wheels: ____]Personalized Output (Generic Example):
Failure Point - Wheel Profile: A completely round-profile wheel may lack a definitive inside edge hold, causing the foot to slip out during the "pull" phase instead of gripping. A wheel with a slight H-block (mild square edge) is ideal.
Failure Point - Boot Stiffness: A boot that is too soft will allow ankle roll, dissipating the energy from the hip pull and reducing power and stability.
Optimization Tip: For most learners, a wheel durometer of 84A-86A provides an ideal balance of grip for the pull and slide for the recovery.
Maintenance Alert: This move causes asymmetric wear on the inside edges of your wheels. Implement a strict cross-rotation schedule (1-3, 2-4, flip).
4. COACHING PROGRESSIONS
Error: Leaning forward at the waist, causing a loss of balance.
Drill: "Wall Drill." Practice the cross-under motion while holding onto a wall, focusing exclusively on keeping the chest up and shoulders over the hips.
Error: Kicking the free foot instead of pulling with the hip.
Drill: "Stationary Pulls." Holding onto something for balance, practice the "pull" motion by isolating the hip engagement on each side without taking the foot off the ground. Feel the glute muscle engage.
Neural Sync Drill: "Slow-Motion Crosses." Perform the move in slow motion, verbally cueing each phase ("glide, set, pull, cross, transfer") to build strong neural pathways for the sequence.
5. COMBO PATHWAYS
WSSF Rule Reference: WSSF Rulebook Section 4.1.2 (Backward Flow). Consistent, rhythmic backward crosses are rewarded in the "Flow" and "Technical Execution" categories for Novice and Intermediate divisions.
High-Scoring Combos:
Backward Crosses → Backward Snake: A fundamental combo that demonstrates control of both wide and narrow backward pathways.
Backward Crossovers → Backward Crosses: A basic speed-to-precision transition.
Flow-State Score: Low Disruption. This move is a core component of backward flow and integrates seamlessly into runs.
6. PHYSICS & SAFETY
Physics Breakdown: The move converts backward momentum into lateral movement through edge pressure. The inside edge acts as a lever, and the hip engagement provides the force to move the center of mass.
Pre-Hab Protocol:
Lateral Lunges: (3x10 per side) to strengthen the hip abductors and adductors used in the pull.
Clamshells: (3x15 per side) to activate the gluteus medius for pelvic stability.
Neural Load Estimate: ~60%. Requires focus on rhythm and timing, but the motion can become largely autonomous with practice.
7. QUANTIFIED MASTERY METRICS
Competition Readiness Checklist:
Can perform 8+ consecutive crosses on both sides without breaking rhythm.
Upper body remains stable and upright; no wavering or arm windmilling.
The "cross" motion is smooth and controlled, not a jerky stomp.
Performance Metrics:
Consistent Cone Clearance: Can perform the move through a straight line of cones spaced 1.2 meters apart without hitting any.
Tempo Maintenance: Can perform 4 crosses in a 5-meter distance, maintaining a consistent speed.
8. VERIFIED PRO TIP
"Think about pulling the floor apart with your feet, not just crossing them. That pulling energy is what generates the power and control." - SeungJin Lee (South Korea), Multiple World Champion

9. ENVIRONMENTAL INTELLIGENCE
Surface Grip Index:
Sport Tile (1.0): Ideal. Provides a predictable grip for the edge pull.
Smooth Concrete (0.9): Good. May require slightly more assertive edge pressure.
Dusty Asphalt (0.7): Not Recommended. Low grip can cause the edge to slip out during the pull, leading to a fall.
Maintenance Impact: High wear on the inside wheel edges. Rotate wheels after every 2-3 significant practice sessions.
Environmental Warning: Avoid wet or oily surfaces. The loss of traction will make the edge set and pull phases unpredictable and dangerous.
Analysis complete. This move is a prerequisite for 72% of B-Tier maneuvers. Mastery is required to advance.
