Well, Nova Scotia is back in lockdown. I did this with my online high school class recently. It's a "Sum of Sequence" kata workout using Heian Nidan. Do movement #1 then reset. Do movements 1 and 2. Reset. Do movements 1, 2 and 3. Reset. etc The formula to determine the total movements you will make is n/2 (n+1), where n = the number of movements in the kata. That makes 351 movements for heian nidan.
