Not necessarily is soreness an indicator of future growth--but your muscles do build up by being torn down in a sense. This tearing down is usually the source of soreness and with proper rest and nutrition growth should occur from taxing your muscles beyond their normal capacity.

being used..tiredness..stress...fatigue..that is what the soreness is...dehydration and other reasons. whether it sores or not, it is never an indication. the only thing you can assure if you did it right and not overtrained..but yeah..feeling that soreness is orgasm

Well for me it depends on the muscle group. With legs it's not so bad the day after, but the 3rd day is a living hell...as for arms it's usually the 2nd day...and chest always is always sore the day after, Don't get me wrong they all hurt the day after, those are the days that the pain gets the worse.

intresting...l dont usally get sore the way lm training...its only when l have shorter breaks between my sets is when l'll feel sore for the next 2 days or so but at the moment having 2min breaks between sets i dont get any muscle sorness.

or if you go heavy..and I mean uber heavy.
