Here is a self-experiment from my e-newsletter. Check the comments for notes about my experience with this self-experiment, then add a comment of your own!
Discover for yourself the power of consistent thinking. To keep things simple, for this self-experiment, you are going to limit yourself to a single thought of the form,
"I allow my ____________ to release."
Fill in the blank with a part of your body where you tend to store tension - forehead, jaw, tongue, neck, shoulders, hands, low back, feet are some possibilities. Whatever part you pick, stay with the same part for the course of this experiment.
Think your thought as often as you remember to, both in repose and during activity. For example, before starting an activity (reaching for your cellphone, getting out of a chair, picking up an object, etc.), pause for a moment and send your thought. Then proceed with the activity. See how often you remember to do this. (And please be gentle with yourself when you forget!)
The kind of thought you are working with is like a wish and is not intended to be carried out. (Movement may occur as a result of the wish, but it should happen because muscles are releasing, not contracting.) Remember that any single repetition of your wish is unlikely to bring about substantial, lasting change; the effects are cumulative and will likely accrue more intensely the more you repeat your wish.
Observe what you notice after working with this wish for one hour. . .then one day. . .then one week or longer. If you appreciate the results, you may want to keep this wish in your permanent repertoire!

The skill I've developed through my Alexander work in manifesting intentions paid off in an unexpected way today.
