Should I be feeling the effects of DOMS/sore every time?

[Try2tryharder]

So for a while iv'e been training by doing my own routine, I was doing 8x5, the last two sets would be repping out. After each workout, especially chest/legs I would get sore muscles. However I have now changed over to doing the 5x5 stronglifts.

Iv'e done 4 sessions now so I know what weights I should be using so that when it's coming to my last set I struggle. Iv'e not been feeling sore after though, my legs a bit because I squat each time but nothing like before.

Does that mean the intensity of my workout isnt enough? I had the impression that (to put it very simply) muscles tear after working out and then when they rebuild = more mass. Therefore i'd assume they should be aching a bit the day after?

Nope, not necessarily. DOMS does not necessarily mean you had a good work nor that you had a bad one.

DOMS are one of those fairly "unknown" areas, we kinda know why and then again we kinda don't know why it happens and it's correlation to growth. For most the DOMS subside over time unless you change your workout routine.

It's not a marker of a good or bad workout and not something you necessarily need to chase after.

If you are progressively overloading you are making gains DOMS or not.

I thought the reason for doms was because of lactic acid build up is this false?

I usually only had intense doms the first week or two of exercise after a long break. After that, minor or no doms, and tons of progress. That's how it always worked out for me.

I haven't seen a study that actually confirms a cause for DOMS yet, most are theories and most have contradictory studies against them.

The closest theory I have seen that "might" be a good cause for it is this:

products of macro****e activity and intracellular contents accumulate in the interstitium, which in turn stimulate free nerve endings of group-IV sensory neurons in the muscles leading to the sensation of DOMS.

Muscle fiber degeneration,necrosis,damage has been disproven, lactate disproven, inflammation disproven etc.. they might all play a small role in correlation though, but still to my knowledge the exact cause of DOMS is unknown.

Ahh cool guys, thats very reassuring. Thanks for the replies
