I have just come in from doing my Tai Chi and Qigong outside. These last few days have been wonderful here and it has been a pleasure to be able to go out and do the Qi practices out in Nature once again. Now, while the ground is still too cold do do in barefoot, dress accordingly and get outside to draw on the burgeoning spring chi.
I strongly encourage you to move you practice outside as soon as practical. There really is nothing like it.
