THE COMPANION BALANCE PROGRESSION : Page 89
DROP KNEES AND ARCH BACK AS BOTTOM MAN COMES OFF
GROUND (c and d);
BALANCE BY PUTTING HEAD FORWARD OR BACKWARD.
KNEE STAND
HINTS TO BEGINNERS: The most difficult phase of this stunt is getting the bottom man off the ground. This is impossible if his heels are not close to his buttocks. If the top man will jump to his partner's knees and go right on over off balance, it will also help to remedy any trouble here.
Note how the top man's weight is brought forward when he drops his knees and arches his back, instead of leaning forward after the "b" position in Figure 78. Advanced tumblers do this stunt with the hand-lock grip so that they can do hand-to-hand balances from it.
