Practising Tai Chi on a regular basis is important for improvement.
However its what you do away from your training sessions that will determine how much you actually improve.
For example when you are working think of the Tai Chi exercises and/or principles you can use.
A simple job as sweeping with a broom is made easier when you focus on your tan tien and not your shoulders and arms to push the broom.
Lifting heavy objects can be made less stressful and safer by focusing on keeping the top of your head in line with your perineum – stops you from arching and straining your back.
Cleaning windows involves the waist leading the arms just like ‘grasping the bird’s tail’ technique in the Tai Chi form.
So use the Tai Chi exercises and principles in your normal work day and you will add many hours to your training sessions.
And improve at a greater rate.
