Insomina, decrease in weight you are lifting. Eleveated morning heart pulse. Ligament and tendon soreness.....etc

If you think you are overtraining then take a week off or something. Also check your diet to see if you are getting the proper nutriton.
Are you doing 5 excercises for tris and bis?
Whats your current split?

monday back
tuesday chest
wed legs
thurs shoulders
fri bis and tris
i do 4 excercises for bis and 4 or 5 for tris usually depending on how they feel. I am thinking of changing it up so i can do each body part twice a week. I don't have any of those symptoms really except for insomnia but school will do that to ya.

I find training 5 days in a row is very taxing on the body. I do a 4 day split. 2 on 1 off and it does the job for me. Also you don't need a larger volume of sets to get bigger gains. Do you train to failure on everything?

on my core lifts i train mostly to failure such as bench and squat. i stay in the 8-10 rep range bc i feel that i don't feel it when i don't push myself for 10 on a really high weight. today i tried the 5x5 on my bench and i am not sore at all. not feeling anything.

Are you going 5 reps max u can't do any reps right after.....Also soreness isnt a sign of progress. I can have a dam good work out and not be sore and others times I can be stiff. Being sore is just latic acid in the muscle.
