Aikido is a martial art style synthesized by Morihei Ueshiba, based on his lifetime of training in many styles of martial arts, most notably Daito Ryu Aiki Jujutsu, but also was influenced by his study in:
Goto Ryu Yagyu Jujutsu
Katori Shinto Ryu
Kito Ryu (Known for projection throws or nage waza; Judos founder Jigoro Kano also studied Kito Ryu)
Kuki Shin Ryu (Kenpo was also taught in this ryu ha)
Takenouchi Ryu (one of the oldest jujutsu style still taught known for immobilization technique or osae waza and kansetsujo. Also much of the judo comes from Takenouchi Ryu Jujutsu)
Tenjin Shin'yo Ryu (Known for its heavy use of percussion or atemi waza. Jigoro Kano also studied, along with Yamashita Yoshitaka. Shindo Yoshin Ryu Jujutsu was also derived from Tenjin Shin'yo Ryu Jujutsu)
Tenshin Shoden Katori Shinto Ryu
Yagu Shinkage Ryu
Falling down and getting back up is a major part of aikido. It also strengthens the body with an emphasis on core muscles.
