Here is another exercise tool that helps you build strength in your back muscles. The Valor Fitness CB-14 Seated Row Machine is made of 2 x 2″ 12-gauge steel with dual-layered padding. It has independent arms, so you can work both sides of your back at the same time.
The CB-14 has a stationary grip handle that lets you target your back muscles like a T-Bar row machine. The seat pad is adjustable to 4 positions vertically while the chest pad has 5 positions for you to choose from.
