Arms against door frame.

Press the backs of your hands against the inside of a door frame for 30 seconds as if you re trying to widen the frame and then let your arms down. A door frame incorporates a number of standard parts some of which are hidden when the wall is covered and the door is in place. It gets difficult after a short while. Stand in a door frame with your arms at your side.

The body frame around car doors is sometimes referred to as an a pillar. In this case when you re pressing against the door frame you are using your up muscles you re pressing outwards with palms facing in activating muscles to lift your arms up which along with sensory neurons that send proprioception information where your body is in space change their tones accordingly and if held long enough say around a minute your brain becomes habituated to the tone. Push your wrists hard against the door frame for a minute. Lift both arms until the backs of your hands are pressed against the door frame.

Your arms will float. After the minute is up step away from the door frame and completely relax your arms. The door jamb is one of the most visible door pieces so much so that people sometimes confuse it with the frame itself. Press hard against the door frame with both arms for 5 to 10 seconds.

Then step out away from the door and just relax your arms. With the arms at the side and the elbows extended press the backs of the hands against the door frame with maximal force for 30 seconds. Why dose your arms raise up. Stand in the doorway with both arms extended to the side of the door frame palms at shoulder height.

Stand inside the doorway looking straight ahead into the room. This is to do with the way in which your muscles control their length because hidden inside each of our muscles is a tiny thing called a muscle spindle and this is like a miniature muscle which has nerve fibres in it and those nerve fibres can tell how much the muscle is being stretched or lengthened. If you have a shorter arm span you might need to. When the time limit has been reached immediately step forward out of the doorway.
