Are you planning to do a challenge for March Matness, Liz (Pilates for Runners) ? Someone on a NHS Health Unlocked forum reminded me of this event initiated by Benjamin Degenhardt over 10 years ago, although it seems to have taken on a life of its own now... It involves doing one (or two) of the exercises of the classical Mat sequence (see photo montage of Degenhardt doing them).   More info is here: https://marchmatness.com/
