i've only been training for about 10 weeks so far, and my bak has had some good improvements (newbie gains) in that time.
because my knees are weak i have to do a separate strength training routine for my legs, therefore, i cant do the FULL deadlift for my bak, because there is too much pressure on my knees.
instead, i do the partial deadlift, and it still works my lower bak very well (just not my legs).
however, yesterday i did a heavy lift, but i felt strain in my lower bak as i tried lifting the bar. so i immediately stopped and dropped to a lower weight, cuz i dont wanna risk gettin even the slightest bak problem.
now, the question is, I'm not sure whether it was my actual spine that was being stressed, or just the actual lower back muscle. it might just be that its my muscles that start fatiging, that makes me feel as though its my bones.
this is how it feels: once i've done the lift, i can feel the typical stinging in my lower back. the one due to lactic acid building up. if i then clench my bak (curve it), the muscle feels more stingy - if u know what i mean.
i need to know if this is normal and that its not my spine which is stressed.
i do keep my bak significantly curved (with my lumbar structure) when lifting.
any help will be much appreciated
