Just noticed some random flicks of Arnold here looking about 35 lbs lighter that usual. Nice phisique of course, but just looks like a normal guy with nice biceps. Is this really how much these guys would shrink in the off season? Was it because they didn't use PCT back then? Wondering if someone could shed some light here.
