The Valor Fitness CB-13, Adjustable Back Extension is a versatile bench intended to strengthen your lower back and build a solid core. Some refer to the back extension as a roman chair. It can be used to perform a variety of exercises. It is commonly used to target the lower back. By changing positions one can target the gluteal, hamstring, and abdominal muscles.

Some of our most asked questions.


Ask a Question
  • Hi, Valor, I'm 6'3", Will this adjust to fit me properly? Thanks!

    The CB-13 has a range of 34.25" to 42.25" for height. I recommend measure from the floor to your hip hinge to see where you would fit between that range. It has 5 adjustment points between those ranges.

  • Where is this product made?

    The CB-13 is made in China
