The Kai said:When you attempt a throw and wind up on the floor, usally means you are caught off balance and helped to the floor.
When performing many throws, the stance that one uses maintains balance and root as one flows into it. We call this stance kyo cha rip jaseh. Your uke's balance and root should be attacked and defeated by good kazushi. As the uke's balance and root is attack, the tori's should grow. If this occurs, nothing can stop the tori from throwing the uke.
Unfortunatly to try a throw you need to step in and commit yourself-hard to attack and reamin rooted.
It's not hard at all once you truly understand what one is doing. Rooting is not static like a tree stuck to the ground. Root can be fluid...yin and yang. The concept deals with ones center of gravity and making sure that it remains in the channel. The physics of rootedness combine Newton's laws with laws concerning torque and laws concerning center of gravity.
The premise behind tai Chi and Aikido is to get out of the way is it not? Again hard to be rooted and move at the same time
Not necessarily.
Kicking which is done with only one leg on the floor by its very nature compromises your balance.
One's center of gravity needs to be "rooted" in order to throw a decent kick.
