Slouch Stopper™
Your complete guide to
a straighter, pain-free back.
Relieving upper back tension and restoring thoracic alignment has never been more straightforward. Two standard tennis balls bonded together form a natural spinal groove — place it on the floor and let your spine sink in, or position it between your shoulder blades to release tech neck and thoracic stiffness.
Simple, effective, and built to go anywhere.
How to use it
Feel the relief in under 60 seconds
Place the Slouch Stopper™ on the ground and lie back, centering it between your shoulder blades so your spine sits in the groove formed by the two bonded balls. Then slowly roll back and forth — you may hear pops as tension releases and your thoracic spine begins to realign naturally.

Meet the founder
Built by the expert who needed it himself.
Hey, I'm Mark, the creator of the Glute Activator™ and the Lower Back Reset Course™.
I've spent my entire 25+ year career studying how the body moves, recovers, and breaks down. I'm a Certified Exercise Physiologist — with a Master's in Science and Public Health and still…
I kept throwing out my back.
I lifted weights. I stretched daily. I played sports. Nothing fixed it. Medication was a Band-Aid. Back braces weakened my core. Inversion tables were bulky and expensive. My PT was never available when I needed them.
"So I built what didn't exist."
