Glad to see my friend Apollo again
Harley: if you look at all pictures of him, everytime he is in a straight he loses headset. Translates into : bending, bending, lateral work. Shoulder ins, legyields, turns on the haunches andNEVER straight.
The same for Apollo. First in a walk only. All lateral exercises, circles, figure 8's, and again, NEVER straight.
You will see a difference in both of them soon.
