I have found that a typical Aikido dojo goes through 'cycles' of training 'style' e.g. If there are a lot of young men that have been there a year or so they are usually very energetic and over enthusiastic with new ukes; if there are a lot of beginners or women, older people or experienced people the practise is usually more measured, or can even deteriorate into lethargy. The club attitude will change as new students join, some students leave and other students advance. Always remember that you are one of those students, and can affect the atmosphere of the club for the better.
P.P.S apologies for my gross generalisations over sex & age & experience. As Chuang Tzu said, 'the seven colours will blind you...'.
