The scorpion stretch is a stretching exercise that focuses on the upper body and into the hip flexors and upper leg.
Start laying face down, flat on the floor
Stretch your arms out as if you were on a cross
Rotate the leg back and behind you in an opposite fashion:
Try and bring your right heel towards your left hand
The reverse is trying to bring your left heel towards your right hand
Try and keep your torso fairly flat on the ground and ensure that your arms and shoulders stay locked into the ground
