I just want to start by saying I am NOT responsible for ANY injuries!
Start by stretching! You should have a full split and a good backbend before you try a scorpion.
This is how to do the actual scorpion!
Of course, start standing!
Lift up your leg.
If you have a left split, lift your right leg. If you have a right split, lift your left leg!
Lift up your leg a bit more. Now start swinging your arm over!
And grab onto your leg. Try to lift it up as much as possible!
Have fun and be safe! And as always, Good Luck!
