It's superior to a. heart rate monitor . It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. Simply lock the bar into position and add your weights. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. 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.
Smooth operation is the key.
