Shotei awase is traditionally taught as an isometric exercise. Isometric exercise or isometrics are a type of strength training in which the joint angle and muscle length do not change during contraction. Isometrics are done in static positions, rather than being dynamic through a range of motion.
From a magazine named “Gendai Aiki”
Gendai budō (現代武道), literally meaning “modern budo”, or Shinbudō (新武道), literally meaning “new budo” are both terms referring to modern Japanese martial arts, which were established after the Meiji Restoration (1866–1869). Koryū are the opposite of these terms referring to ancient martial arts established before the Meiji Restoration.
Gendai Aiki is a subcategory of Gendai budō. It is during a short period used to define Tomiki Aikido. Shin-Aikido was also in use during this time.
The pictures are showing the traditional exercise and some applications.
A wall can be used as a replacement for a training partner
Shotei awase – a pushing exercise without pushing
Shotei awase can be used to study “body block”.
When applying power for example forward, there is always a backward component when partner is resisting.
By using “yukozo” you can keep a strong posture. Tensing up by pulling the muscles will have a negative impact on the posture.
Notice the hand on the back. The backward movement creates a slightly roundness in the lower back.
When you push the lower back forward, the knees becomes stiff.
Bracing the back leg (knee) has a negative influence on the concept of yukozo.
Putting the weight on
Taïjū no dendō or transmission of body weight. Shotei awase is “not” about pushing, but about putting the body weight into the training partner.The muscles becomes of course under tension, don’t tense activily the muscles.
It is possible to lift either the left or right foot and still have a body block.
Body block is not only used during shotei awase, but has many applications.
Putting the weight on is a clever application of gravity while keeping control.
