This video demonstrates how to perform reverse crunches using a stability ball, an exercise designed to build core strength through spinal flexion initiated from the bottom up.
While lying on your back, you will pinch the stability ball between your hamstrings and heels, lifting it just slightly off the table.
The movement focuses on gently curling the tailbone upward rather than engaging the upper spine. This is a controlled, low-impact exercise well suited for patients working to improve lower core stability.

Reverse crunches using a stability ball.
So you'll lay on your back. You'll pinch this ball using your hamstrings and your heels. And you're just really going to elevate that up just off the table about an inch.
And then it's these reverse... ...crunches.
And with this, you're really just trying to take that tailbone and just curl it up, just gently off the table a bit. Not the whole thing.
Reverse crunches using the ball.
And this is to help to get that spinal flexion not from the top, but from the bottom up.
