I can see bones in my chest.?!

I can see bones in my chest.?

First off, I am not anorexic or anything. I am a 16 year old male, I am 5'6 and around 130-135 pounds. I am the average weight for my height, so I am not skinny. I can see a few rib textures in the middle of my chest, especially when I raise out my arms. I work out a lot, you know, benching and curling and jump rope. I can't stand my chest, even though I have a lot of muscle there it is just bone in the middle. Is this normal?

yes. i had the same thing when i was about 15. just keep working out and you'll start to fill in, it just takes a couple years. i weighed 115 when i first started working out at 15 years old. I'm 23 now and i weigh 170lbs.
