I did legs on Monday night and usually do them towards the end of the week, but I'm trying to switch up my routine. I didn't do them last week at all because I wanted to give them a good rest before I changed up my training schedule. Well, I went really hard on them on Monday(I mean really hard). I was completely spent when I was done and felt kind of nauseus and drained. Well I got home, had my post workout shake and meal and then layed down for about 10 minutes on the floor. I got up and felt very sick and had a really bad headache, and very week. Almost like I had the flu or something. I had tons of heat radiating off my body, but I felt really cold in the shower so I had to take a really hot one. Well I went to sleep and had a very restless night. I woke up a few times feeling like I got hit by a mac truck. Well Tuesday morning I woke up and felt like I had a hangover( I haven't had one before but people have described them to me). By that evening my headache was almost completely gone and I felt pretty good. I worked out my chest, but by about an hour later I felt the same! I had the same sleep pattern last night and woke up today feeling the same except my legs are super sore from I'm guessing DOMS. I can hardly walk and I haven't ever felt like this before because of working out. Sorry for the long post but could I have overtrained in just that amount of time. I'm feeling better as the day goes by but it's still not good.
