So, after reading from many sites and a few books I have realized that only a few consider a half squat a squat? Is that right? When I squat full my knees crack like mad and kinda ache for a day or two. Only to squat again to ache again. This achy knee thing starting yrs ago, unrelated to lifting. All my brothers (3) have bad knees, my dad too as well as all his brothers (my 4 uncles). Maybe funky knee genes? Anyway, question is, is it still worth doing? As in, will my legs and rear still benefit?

Regardless, I totally love it, lifting weights has become a love for me now.
