Seriously ankle strengthening exercises are so good for keeping yourself in dance shape during extended time away from the floor.
I developed a bum ankle during the early pandemic but the exercises fixed it, along with the dance wobble I had developed from not dancing for so long.
I stand on the ball of one foot, heel off the floor, for a count of 60 each side. Then one footed releves, set of 20, without holding onto anything. I try to do it every day. Only takes a couple of minutes and it's really helped.
I would also recommend beginner ballet trainings/barr fitness exercise which are also very good for developing core, ankle and leg strengths in general (basically doing similar things as the ankle exercise). Especially if you enjoy classical music, I find it super meditating. Now I found a studio near me they have class with a pianists playing live, the sound echoing off the high ceiling of the studio, and you are just focusing on controlling your body doing some simple moves, just yourself and the music (with only one instrument) and nothing else
Interesting thing was that I actually danced my best, or at least I felt like it. Probably people were right when they said that sometimes a break is the best what you can do.
