Hypervibe’s pivotal motion produces significantly less head vibration than the lineal motion of the Sonic machine. Due to the more natural motion of a pivotal, the pelvis is rotated, and forces are absorbed by the trunk muscles and not up to the head. This makes it safer, better for lower back muscles (only pivotal shown to reduce back pain), and users naturally prefer the pivotal motion.

When compared directly in a single study, or through meta analysis, Pivotal machines have shown greater effect size in topics such as bone density and circulation, and muscle activation. There is no evidence of decreased back pain in a Lineal machine, as mentioned above.
Hypervibe machines produce significantly more G force than most lineal machines. The amount G force determines the exercise load, and has been demonstrated many times to increase the size of the effect on muscle activation, oxygen uptake, and perceived exertion.

In a 2012 comparison of over 41 different vibration machines, engineering test results showed that on average, the more G force a machine could produce, the more expensive it was.
The G force output of a Sonic machine is 3g’s or less and has little difference in G force output to those of machines which cost as little as $200 on eBay. With the very high price tag of Sonic machines, this makes the Sonic machine one of the worst value machines on the market!
The +10g vibration specifications of Hypervibe machines are only found in machines which cost many thousands of dollars more.
