1/4 spring

By Donna Vande Beek, ON, CA on February 06, 2021

So happy to have a 1/4 spring on my reformer. It can work your abs more intensely in certain exercises as you just cannot let go.

I love my Spring Wall

I love my Spring Wall and my friends are jealous. Best investment I made in workout equipment.
