When we find Tai Chi in our middle years eg 30+ then we may well be looking to put a good amount of effort into our practice and perhaps to explore the martial aspects. Fortunately the training at this time is the same as for other espects but with the emphasis on loosening, improving structure and building resilient strength.
There is ample opportunity to explore the literature, the videos and the courses available, and you are likely to have the resources which enable you to invest in your practice.
