I need the muscles!!

being a nurse requires a lot....and one of it is the muscle to carry heavy loads - as in the patients. Moving them and etc. We had some practice yesterday and well, today i'm aching all over T.T Reason one for the aching - not using the right body mechanics. Reason two - my body muscles are not used to it. Well, it'll need lots of practice and that means that i'll be aching for a long time....hope that i get it right soon....
