In my training sometimes i think i hit too much, not feeling overtraining but i guess i don't rest enought for the intenity of the training.
Maybe i should lower the number of exercices.
Usually i do 4 exercices for the muscle group, maybe i should lower to 3 doing 15,12,10,8,6 increasing wheight.

Im saying this because if hit twice a week and i don't rest between, than 6 exercices a week for muscle group should be enought, except for legs because im a strong beliver that the legs must train more and harder than any other muscle group
