Aiki is a throwing art that usually requires Nage to be very close to Uke and then take Uke's balance. For this reason the two basic skills of Aiki are:

1. Close with your partner.

2. Take your partners balance.

As you will see below, when Nage has closed with Uke and taken Uke's balance, Uke is in a very compromised position. Aikido techniques are usually not necessary. Almost anything can be done as a technique.
