If you get a chance during this fine weather do find a space to do Chi Kung outside. You do not have to go through the whole sequence. Go from standing with arms by your side (1min) to the first position, 'Lifting the ball' (5mins), then bring your hands to your centre and straighten your legs and stand (1min).
[The MDA timer or any meditation app timer can be helpful]
Then do ten Phoenix Rises. And if you can, maybe do the Foundation form. If not, do walk a little afterwards anyways.
If you are curious, try it for a week, and see how you feel afterwards. If possible do it in the morning, first thing after you rise. Set the alarm clock ten minutes earlier than normal. Let us know how you get on.
Enjoy the sun!
