what does your Wikipedia reference-linkMRI report say ?

A warm up and a cool down.. Not a cooling exercise...
Warming up should at least consist of the following:

5 to 10 minutes walking -jogging - to increase body temperature
10 to 15 minutes dynamic stretching exercises - reduce muscle stiffness
5 to 10 minutes general body exercises.

Cooling down should consist of the following:

5 to 10 minutes jogging/walking - decrease body temperature and remove waste products from the working muscles
5 to 10 minutes static stretching exercises-- Hold the stretch for at-least 10 seconds...

you still have not mentioned if you are diabetic or not..
