I'm loving her off-season look, but I disagree with elma - her arms really haven't improved noticeably over the off-season. If you compare her double biceps pics over the past 6 months, they're pretty much the same. Any extra arm size she has now is just fat/water. The more noteworthy thing is the increase in lat thickness. That is actually an improvement on last year, and I reckon we're going to see more thickness in her chest too.
She might need a bit more leg size, though we know that her leg conditioning is outstanding in competition shape
