Smooth operation is the key. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. Simply lock the bar into position and add your weights.

Smooth operation is the key.
Utilizing a double circuit linear motion ball bearing system, the load is supported by several lines of balls inside return circuits which infinitely circulate com one side of the retainer to the other. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter.
