On the other hand, being able to train by yourself in choreographed solo forms is also the great blessing of the Chinese systems, including the internal martial arts like taijiquan. At no time is this more evident than in the current pandemic crisis covering the world. Dojos and gyms are forced to close temporarily; group classes in public parks are curtailed and everyone is being told to skip contact training as much as possible to protect everyone involved, at least in the short-term until the infection rate slows and/or a vaccine is forthcoming.
However, with solo forms training no one else has to be at risk if you want to train and can find the space to practise in relative isolation. So, make sure, along with the normal conditioning routine that is appropriate to your age and state of health, that you double-up on your regular solo form training routine. For example, while my partner-training sessions are on hold as they are now, I am maintaining a schedule of varied solo forms both in the morning and in the early evening every day while this crisis and being house-bound lasts.
