Simple home gym hack that lets your BulletProof Isolator perform better hip thrusts, enabling free-spinning movement on the seat preacher curl attachment. It's a simple adjustment that can greatly enhance your glute exercises and your overall workout experience.  It allows the seat and preacher curl attachment to spin freely for better hip thrusts.

I edited a second model that's slightly thicker. It won't go over the outer, but it's a little stronger and more secure when holding the pin in place. You just can't slide it onto the top of the pin like you can with the original model. Both work fine, just a matter of preference.
