Sorry if im taking over thread buy asking this Question.

Ive got it in my mind that when i go to the gym depending on what body parts am doing ive got it in my mind that the next day i should be aching.Ive got to the point now where i dont ache the day after.

I can be doing my biceps for example and i get them to start burning in the gym then the next day i still dont ache.Do you rhink i should change my routine,if so what do i do diffenrently.
