Zero Balancing, Alexander Technique and Learning to Relax Whatever You're Doing
Being able to relax is one skill. Learning how to be most relaxed whatever you're doing is something much more valuable. To some degree the former leads to the latter. If you're more relaxed when you start something, you'll condition yourself to be more relaxed while doing it. Like breathing, make relaxing something that you automatically do all the time.
Richard Bandler taught me a technique from Zero Balancing. I know it's not the whole of Zero Balancing but I highly recommend applying this particular principle:
All you have to do is pay attention to how your body responds to gravity. The idea is to keep your muscles as relaxed as possible whatever you're doing (whilst maintaining good posture).
Standing up for example: it's a bit like stacking wooden blocks. If you don't
balance each part of your body properly then your muscles have to be excessively
tense to make sure you stay upright.
Start by finding the perfect balance point of your lower spine on top of your
pelvis, by keeping your upper body rigid and rocking forwards/backwards/side-to-side
at the hips.
Then do the same with your middle spine on top of your lower spine, then
your upper spine, neck and head in turn...
... you will feel a very distinctive and pleasant sense of "zoning out".
That's what you're aiming for.
You can do this whether you're standing or sitting. You can also use the same principle during movement, although it takes more experimentation to find the most "balanced" ways to do something. For example, the Alexander Technique recommends rocking forwards slightly when climbing stairs.
