Alina's biceps aren't fully flexed in that pic, although Sarah does have incredible biceps which are arguably the best in the world. Kim's all shoulders and arms(and chest to a lesser extent). Alina has the best overall physique. Looking forward to weekend recon Alina will be 2nd or 3rd. Kim and Sarah could possibly make top 6 even with their relatively poor leg development. Legs in the last few competitions seem to have been overlooked, maybe that's because many female pros don't have great legs?
