Muscles, tendons, and ligaments, and fascia do it just as the spokes on your wheels.  Break a spoke, and the tension becomes unbalanced.  Your wheel becomes untrue.

Balance your tension and you have equilibrium.

With thought, we alter tension and pressure, whether hydrolic or magnetic.

Let go of unnecessary pressure.  Balance the tension.  You now have freedom of movement.  You now have better ability to feel rhythm whether playing music, swimming, cycling or running.

Balance tension and feel rhythm.

Rest well.
