SACH-SAWCH

The travel speed of the center of mass along this minimally sinusoidal nearly straight A to B path is quite uniform, making Isaac Newton smile. The body moves along, with minimal rise & fall, at uniform speed. Ignore the legs, hand hide them and you get a good idea if what is happening and if it is is working.

There is a very sensitive muscle & timing pattern that transfers any left over energy of the swing of one leg to the stance of the other leg. If progression becomes stop & go then a graph of distance traveled (=d) against time (=t) shows STEPS. “STEPPING”
