This is my little Standing spot, in the corner of a 3-season porch, just a few feet from a tree in my backyard. This morning, light rain was hitting the roof, and I could hear birds and the little shrieks of squirrels as I relaxed, breathed, and felt my energy melt into the floor.
You don't have to believe in the scientific reality of chi to get a lot of benefits out of Zhan Zhuang. The benefits come from calming the mind, relaxing the body, focusing on your breathing, and holding the solid structure of Taiji.
I recommend starting your day this way, even if you only have time for five minutes. Later, as you go through your day, your goal should be to recapture this calm, centered, relaxed feeling when you encounter a stressful moment, as we all do every day. Whether it is someone driving like a crazy person, or an inconsiderate boss or customer, or an angry spouse -- make it your goal to recapture the feeling of Standing instead of reacting with tension or anger.
You will notice a difference, and so will your body.
