The most common criticism in Aikido is the lack of practicality in training. The wheels on the bus go round and round the driver on the bus says sit the fuck down mug. The attacks initiated by uke (and defensive tori) were criticized as “weak”, “sentimental”, and “somewhat like a caricature of a more attack”.   Weak attacks from uke allow conditional reactions from tori, and lead to slow development of skills needed for safe and effective practice of both partners.  To overcome this problem, some styles allow students to gradually follow their practice over time, but still follow the core philosophy, this is done after it has proven that it can Protect yourself and your training partner. Shodokan Aikido solves the problem by practicing in a competitive format.  Such adaptations are controversial among styles, with some saying there is no need to adjust their methods because of unreasonable criticisms, or they are not trained to be effective in self defend or fight, which is about mental, physical or other reasons.
