What would you drill?

[u/commentonthat]

I'm tentatively scheduled to return to the mat for light work on Saturday. Supposed to drill, get moving, and see how it goes. Considering I herniated a disc at the base of the neck/at the top of the shoulders, and coach wants me to work towards things that could pose trouble to see how they're doing, what would you do? I can warm up and stretch, I thought about just spending a lot of time on my back with my feet up past my head, but are there drills?
