developing back portion of ring swings

Anyone have supplemental exercises/drills to develop the back swing of ring swings? (That don't require a spotter!) Thanks

Arch rocks to locust position.

We used to do this drill. Stand in front of an inclined wedge at the top. Drop/flop forward and drive heels to ceiling.

Upper arm swings are sort of similar in a sense but the positions of the tap are more like HB. You can work towards doing a shoulder roll like an inlocate or dislocate from upper arm swing.

perfect, thanks.
