Sometimes, it seems we take sideups for granted. It's understandable. We count them awful fast on OTC days. And after you've done them a couple of dozen times, they do seem a bit easier.
If you don't feel like you are getting all of the possible benefits of sideups, check out the video below. It has some cool tips on how to form them up. It even shows a cool new progression that Kate R. discovered that will take the difficulty level (and benefit) up a notch - or two!
