If you are not familiar, this is the shuffle dance.
And here is a video that says you can learn how to do it in 5 minutes.
Note how each foot hits all 3 positions: front, middle, and rear.
I have been trying for 2 weeks and can only manage 5–10 seconds before losing my place. I am winded after 20–30 seconds.
Some of them look like they are floating. Are they doing this on the Moon?!
This shuffle stair challenge blows me away. I’d be found dead on the basement floor with 2 broken ankles and a head injury if I tried it.
If you can do it, what is your secret?
