Here is an easy way to go into a partial trance while walking or jogging. Be careful not to go too deep a trance. If you feel yourself slipping out of reality shorten the distance gap between yourself and you. Never allow yourself to go so deep that you become unaware of curbs and cars. Be careful with this, please!
The reason to this this is as you pull your attention in you will also have reduced anxiety. Basically you are going on autopilot. Anxiety and hypnotic states don't mix. So even the lightest hypnotic state is going to drastically drop and feeling of social or general anxiety.
As you are walking imagine walking about 5 feet behind yourself and seeing your body walking. The more you focus on imagining seeing yourself the more inward your mind goes. At some point, your mind is so busy recreating the image of you walking it is split between that and looking ahead.
Now, once you have that down and if you are not putting yourself in danger. You can enhance the image of yourself to be a more fit version. Notice how this will increase the reality of obtaining that physic and the effort will increase naturally! This is because you see the effect very clearly of the exercise you are engaged in at that movement, shortening the cause/effect distance to one where you are more aware of how every step is taking you to your goal as you make them.
