Hi there,
So I've noticed that I've developed a dent between my breasts kind of like the vertical line seen
here that runs from her bikini buckle to her belly button. It wasn't there before.
I've been weight lifting every day for the past month and this dent has become defined. I was wondering why that is? It feels like the separation between my rib cage but not all of my friends have it.
Mine isn't as noticeable as it is in the pic but I was wondering whether it was due to weight loss or due to muscle gain? Could it be the formation of abs?
Any insight into this would help. Thanks!
