I know it takes women a LONG time to build muscle, so I'm wondering what this is. For about a month I've been doing lots of boxing on the Wii. Before, when I bend my arm in the "show my muscle stance," my biceps were soft and mushy, no hint of a muscle lol. Now, I can barely bend my arm to do the "stance" and you can clearly see and feel a pretty good lump of something. Is that muscle? My friend says it's not likely muscle because women don't build muscle that fast. I thought it was swollen parts due to boxing or something but it's been there for a while now and it's there even when I stop boxing for a few days. Could it be true? Is that lump muscle?
