Either way, you must respect your body and allow ample time for recovery from working out/exercise, specially when your body tells you so!
Try to alternate between heavy and light, aerobic and un-aerobic, upper and lower body-well you know what I mean- and proper rest in between
If you have any inflammation, infection, fatigue, stress, that's a sign to slow things down, because if you don't, those conditions WILL!
