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. Face a wall, drive the knee forward to touch it while keeping the heel down. Target: toes >13cm from the wall.

Coaching cues
- 1.Heel stays down the whole time
- 2.Knee tracks toward the second toe — no valgus
- 3.Do daily, 30s holds
- 4.Target 13cm+ toe distance

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)
Couch Stretch
Targets a key jumping muscle — the couch stretch focuses on the rectus femoris (the biarticular muscle that flexes the hip and extends the knee in jumping); tightness significantly lowers drive efficiency
