How to do: 90 Degree Abs Slider

Start in a high plank position with both feet on sliders. Slide right foot forward and across your body, as if aiming for your left shoulder, as you lift left hand off ground and rotate to the left (so all your weight is on your right hand). Tap your right knee with left hand before sliding back into a high plank position. Repeat on the other side. Make it easier: Instead of sliding walk the corkscrew as described.
