- 3.Do it daily as ankle maintenance
- 4.Especially important in injury recovery — prevents stiffness

Ankle Dorsiflexion Stretch
A key limiter of takeoff depth — every 1cm of ankle dorsiflexion means a deeper takeoff angle, longer force application and higher jumps
Hip Flexor Stretch
Unlock hip-extension potential — limited hip extension is associated with reduced takeoff drive, and hip-flexor stretching can help restore it
Thoracic Spine Rotation
Unlock arm-swing potential — thoracic rotation directly affects swing amplitude and jump efficiency (the thoracic spine should contribute ~35-40° of rotation)
