Walking down the street most people take in the sights of their surroundings such as buildings, plant life and other things that grab their eyes. Especially while living in a city with many people, you can't help but notice what people are wearing, their faces and facial expressions. I use notice that all before but now it's a little different for me. Now that I'm a personal trainer and that I work with people's bodies and understand the human body more than ever, I notice things that most people don't, posture. 90% of the popluation seems to have horrible posture. I find it sort of amusing walking down the street or sitting on the T looking at people and noticing what muscles are tight and weak on everybody. Usually the guy who is all dressed up in his suit, he's got to be making tons of money, looks sleek and sophisticated but if you look down at his designer shoes they are pointing outwards ( in this fashion \/). When the feet are externally rotated 9,000 things run through my head on how I could get rid of that. Then you might see a girl walking down the street with the same problem and usually has a slight bounce to her step if I go ask her if she wears high heels there is a 95% chance she will say yes. Then usually will say her calfs bother her. Then people slouching on the T with their internally rotated shoulders and heads tilted forward tell me that people are sitting in front of the computer for hours and have horrible posture. Most people are shooting themselves in their foot when they have horrible posture because we've all seen the 80 year old man walking down the street with a hunch back and head that is way out in front. I believe horrible posture is the reason why people shrink with age. Anyways, next time you walk outside notice how horrible everyone's posture is and notice if you might have bad posture urself. Ask me and I can help you change it.
