Perfect Double Under Technique

The double under is a jump rope skill where the rope passes under your feet twice in a single jump. This high-speed movement demands precise timing, efficient jumping, and consistent wrist rotation. ChAIron's AI coaching ensures optimal rhythm and technique development.

Step-by-Step Form Guide

  1. Setup Position: Hold rope handles with relaxed grip, elbows close to ribs, rope behind feet
  2. Jump Initiation: Jump slightly higher than single unders, staying on balls of feet with minimal knee bend
  3. Wrist Rotation: Accelerate rope speed with quick, tight wrist circles while maintaining elbow position
  4. Landing Control: Land softly on balls of feet, immediately preparing for next jump cycle

Common Mistakes to Avoid

  • Jumping too high or using excessive knee bend
  • Moving elbows away from body during rope acceleration
  • Inconsistent wrist speed leading to timing errors
  • Looking down at feet instead of straight ahead
  • Tensing shoulders and upper body
