Hi Matthew. There is a handy wee book called "The Anatomy of Runner" by Jay Dichary.

In it there are tests for posture, stability, strenght imbalances etc.

It took me half an hour to complete the tests (with help from my partner).
There are then exercise to start for correction etc.

It is all pro-active positive stuff.

(There are other books out there this one worked well for me)

It also gives guidelines on when to run and when you cant (i.e favours running).

I had calf tightness on and off for the last 6 weeks. Dusted this book off, and finally im getting stuck in and getting places.

It works and good for the head to feel youre taking action. Recommended to buy, borrow or steal.
