jessekaiser 56:6ea03cce1175 2 Some variables are also numbered at the end. The numbers stands for the muscle that controls it.
jessekaiser 56:6ea03cce1175 3 Biceps = 1
jessekaiser 56:6ea03cce1175 4 Triceps = 2
jessekaiser 56:6ea03cce1175 5 Pectoralis Major = 3
jessekaiser 56:6ea03cce1175 6 Deltoid = 4
jessekaiser 56:6ea03cce1175 7 The "x" and "y" at the end of variables stand for the X-Spindle or Y-Spindle respectivly.
