I have been sick for almost 2 weeks with pneumonia. My doc says to not work out when I'm sick cause it will prolong the sickness. The problem is I'm on the last three weeks of my cycle and I feel like I'm wasting the time I have. On the other hand i want this to be done with asap. Will working out while I'm sick make it last longer? Also I have very little energy but I figure going and doing something would b better than nothing.
