whoapandaPhysiologically, what might it mean if I have a much easier time holding myself with straight arms above than with bent arms around face height? Would that mean my back muscles are better conditioned than my biceps/core?

VeenaWhen the arms are extended you're relying on the larger muscles of the back to hold you, this is easier for most unless they are heavy for their size and have poor hand strength. Lats and traps are much bigger than biceps. Holding with bend arms requires the biceps to do more of the work.
