It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. 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. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings.
Smooth operation is the key.
Simply lock the bar into position and add your weights. The Best Combination. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter.
