whenever i take a break for a 2-3 weeks and start working out again i'll get sore the first time i work out that body part but not after that. i thought maybe my body responds differently to building muscle and i don't get sore, but recently i threw in some new chest excersises and for the last 2 months my chest gets pretty sore for as long as to 2-3 days after every chest day. i tried throwing in new things into my other bodypart workouts but they still don't get sore. does that mean i am not working them out with enough intensity. also have another question is it bad to workout a bodypart ocassionally with only one day of rest in between. thanx for help.
