If your lower back aches by teatime, you have probably tried most of the usual answers. A hot water bottle that goes cold in twenty minutes. A support belt that digs in and does nothing else. A massage gun that is awkward to aim at your own back and impossible to hold there for long. Painkillers that take the edge off and leave the cause exactly where it was.
Each one does a single job. The trouble is that a tired lower back is rarely a single problem: the muscles are tight, and they are cold, and they are being asked to hold you upright all day without a break. Fix one and the other two carry on.
That is the whole idea behind the Vibraflex. Do all three at once, for fifteen minutes, every day.
