well it seems like your not a morning person for starters. also It seems as if youve been doing your workouts in the afternoon for some time now. I get this a lot too. I have college and on some days im forced to do morning workouts and somedays I can go whenever I want. your probably not feeling the hurts because you never applied enough weights to feel the hurts. my recommendation for you is to pick up some pre-workout supplement to help you get that morning going and your workout as well. it may work wonders for you. It has for me.
