Throwback Thursday - Fitness Blender Style

Hey Blenders,

Throwback Thursday exercises! Say what?

I was just looking around and came across this video, which shows

the very first appearance of the sumo squat from Kelli - circa 2010! It has been viewed A LOT, so evidently people are still using it...I guess.

So, question of the day - do you have a favorite OLD video from Fitness Blender? One that you still use, maybe?
