Been working out... why no more lactic acid pain?

[RIGorous1]

I've been working out for nearly 7 weeks now (in the gym about 6 hours a week) and after the first 2 weeks I've lost that lactic acid pain (a pain that I kind of like)... I've upped my all my weights incrementally and my muscles do fatigue;however, I never get that soreness the next day anymore. What's going on here?

It happens. I am able to get post-workout pain the next day in chest EVERY time I work chest. I'm able to with biceps only after a long break or unusual workout. Dito for most of my muscle groups, with shoulders being the hardest for me to get this soreness from. It's normal.

Keeping with a routine keeps most of the weekend warrior syndrome at bay.

I believe you get lactic acid pain when your muscles can't get enough oxygen during the workout. After a while, your muscles become more efficient, therefore they get enough oxygen and eliminating the lactic acid pain.

Or I could be totally wrong...

Most bodybuilding articles I've read note that post-workout soreness doesn't indicate a successful workout...
i.e. a good workout doesn't have to make you sore the next day.

you must be a machine.
quickly cut open your arm to find out.

you don't get that painful soreness after the first couple weeks.. though i am sore after a heavy weight workout (instead of high rep)

lactic acid pain is a myth.

Blood vessels carry lactic acid out of the muscle. Lactic acid is a byproduct of your working out -and, if too much is accumulated (if the blood vessels can't remove it fast enough) you get cramps in that muscle. Anyway, the more you work out, the more your body builds a bigger network of blood vessels throughout your muscle tissue to accommodate for the higher requirement of nutrients, which allows for the lactic acid to be removed from the muscle at a greater rate.

However. The pain you feel in the morning is not because of lactic acid.

I keep reading about how the pain is from microtears, the basis of muscle growth. If you're not getting at least a bit stiff you may not be working out enough or hard enough. You say you lift to fatigue (the point where you physically can't do another rep), which is good - but are you doing a light weight for 20 reps or a heavy weight for 6-10? Heavier is better for muscle growth. Also can try doing more sets, if you do 3 like many people. I'm focusing on my chest, arms, and quads, and do 6-8 sets of the exercises that target them. I've noticed a lot more growth and stiffness since upping the number of sets. After a good chest workout I'm stiff for about 5 days. Your body will also adjust to what you're doing after a while, so as to do the required task with the minimum amount of energy expenditure. You have to switch up what you're doing or how you're doing it generally every few months.

you aren't doing heavy squats to below parallel
or heavy deadlifts. try some & you'll get your
soreness back.

Because your body is used to the pain, and your mind is "programed" to ignore that pain.

I thought this thread would be about gastrointestinal pain, or heartburn. Cause I used to get heartburn all the time until I started excercising. Now its' gone!

I don't know why muscle cramps are caused by "lactic" acid. Doesn't lactic mean it has something to do with milk???
