Be aware of Yin & Yang in your form – e.g. Left leg forward: Left leg & right arm are Yang – Right leg and left arm are Yin.
When extending your arms – don’t lock your elbow joints – leave some Yin there (slightly bent).
When you practice the Tai Chi form focus on one theme only e.g. breathing, balance, Yin Yang, alignment etc.
Balance on one leg – Focus on the chi going through your supporting leg into the ground & deeply spreading out like tree roots.
Tai Chi Form: Avoid knee strain – keep your knees pointed towards your toes and make sure the knees don’t go past your toes
