Like you im a firefighter aswell. I know what you are going thru with muscle wasting. I love the gym and now i cant do a thing for at least 3 months. my left leg is now smaller than my right. Dont beat your self up over this as it is not your fault. I hope they got the [email protected]# holes that did this to you. Just remember you have a fellow Firefighter going thru the same thing right now.
Take care Brother.
