Dance photos

Our local studio asked us to take photos at this year's end if year dance show. Normally im shooting sports in a fair amount of light, but this is in a preforming arts center. Any suggestions on how to make my life easy?

Canon R5 will use the 70-200 2.8 lens.

Last year I shot with my 60D and a loaned lens, and had sub par results, which drove me to upgrade this year.

Edited 70-200 ap because I was thinking of my 35mm lol opps
