Thanks for the replies guys, I was determined to do 120 today, but my form was bad and I'm feeling it now.
I'll try to work around it on wed and fri i think, am fine to bench, can do some wide grip chins, just my squats and overhead press will be out of the question I think as its real stiff now, lol fuuuurk.
I been trying so hard to get my bench to 100kg, squat to 140kg and dead to 180kg, that i guess I am rushing it to much. I'm gonna focus on my form when I get over this and work the weight up from there.
Still, it feels good to know that I actually squated 120kg, even if it fuurked me, was only a few weeks ago I got stuck at 85kg lol.
