The Corkscrew starts with the Roll Over. So if you aren't to the Roll Over yet, this one will be modified as well.

You can modify by keeping the legs bent and just trying to direct your knees to one side at a time.

The full exercise involves circling the legs completely around- once to the right, and then once to the left.

So it's :

a roll over up the center

circle legs over to the right, down and then back up overhead

then circle legs over to the left, down and then back overhead,

finish by rolling back down the center

that is one!
