When i thought about it, the burpee.. Burpee - https://www.youtube.com/watch?v=UunbfaoJmxg
When he jumps two footed and lands with his feet sidewards to get over the bar or box wouldn't that be the same as the previous way we did burpees over the bar/box. His feet land at different times! so if you let one leg hang back you will more or less be doing th esame thing as before.
The only way for them to define this correctly is if they actually say it is a 2 feet take off and a 2 feet landing.
This will make it impossible for anyone to side step later.
