Simply lock the bar into position. Simply lock the bar into position and add your weights.
Smooth operation is the key.
The no-impact nature means there is less stress placed on the joints. The Best Combination of Raw Power and Precision Design. 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. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability.
