Has anyone else ever had this happen? I have been getting back into the workout scene the past few weeks and recently I will go pretty hard and not feel to bad the next morning or most of the day. But like today I wake up 2 days later and definetely feel it. Wed. night I did my back routine and no my lats and traps are really sore on Friday but yesterday I only felt it a little. The same thing happened earlier this week after my chest workout 2 days later my pecs were really sore. I just wondered if anyone knew the reason for this.
