Sorry D, I did not mean it like that at all. Pain syndromes are actually very common these days because most of us do not get enough of the right type of motion daily. This is due to our very linear lifestyle (t.v. driving computers cell phones).
Pain expert Pete Egoscue calls this living in a box. Our bodies are designed for very dynamic movement but most of us just operate in this tiny box.
Every single client I've worked with in the last 6 years has had multiple pain issues.
For women it's usually upper back, knees, shoulders, wrists, neck
For men it's usually lower back, hip, glutes, shoulders, elbows, knees
Sometimes you fix one problem and another one pops up shortly after. I'm actually working with a lady now who's had horrible TMJ (knee and shoulder issues in the past as well). We seem to have all that under control but now it's her low back.
Doing
mobility exercises daily for about 5-8 min. can make a big difference. I do these daily before workouts or mid day if I'm feeling stiff from too much computer work.
Here's a super quick
mobility routine from my primal workout series that is so easy and would actually be ideal for your knee issues!
