Auuuouuch!

In the human body there are about 650 muscles.

Last night i hurt my back during the body-combat class.
In fact the pain started last weekend, during my first time of the year, snowboarding outing , due to some really nasty falls.

then i had the great idea of going running and rowing, on monday, which didnt help, and finally yesterday a body-combat class without warm-up.

result: big pain and one night without sleep.
