2nd Med school block exam this friday

Been taking some time off out of the box to study and also to give my body some rest. Seems my asthma symptoms have come back a bit. Its become a problem in a few of the WODs. I did the 300 WOD, and could not catch my breath for a long time. I went very hard on the first half of that workout and paid for it. Did another workout that was designed like FGB with some less conventional exercises such as tire pounds with a hammer and sandbag get ups, lungs closed up on me again. I'm not making excuses, I'll still go in with time permitting, just gotta make sure I don't die. Frustrating. At least I'm still getting stronger.
