Power Racks make it possible to lift weights safely even when you are working out alone. You can do bench presses even without a spotter When you use the power cage. Simply set the safety bar catches at a level just above your body. If you fail on a rep, the bars will catch the weight, leaving you unharmed. Squatting inside the power rack makes using the heavy weights much safer. You have the reliability of solid steel construction that will catch the weight as opposed to your spotters. Most power racks also have a pull up bar across the top of the front side. This added feature makes the rack more versatile. Another great feature is that most of the power cages we sell also have the option to add a lat pulldown and low row attachment. When you add the lat & low row attachment to a power rack, you increase the functionality of the rack. The vast number of exercises that you can do with this attachment makes it a valuable investment.
