What to do after 10,000 swing challenge?

I have one workout left to complete the 10,000 swing challenge. I’ve been using a single 25kg bell. Two handed swings seem fairly easy at this point. I was debating trying the challenge again with one handed swings.

Does anyone have any recommendations for a new routine? Something with a 25kg single bell would be ideal. I’d also consider going heavier but not sure if it’s needed at this point.
