My ribs stick out far too much!

My opinion - your ribs look fine - you look like a health person. And, flawed though the BMI scale may be, you are in the "normal" range.

to answer your question - No. There is no exercise or diet that will reduce the rib cage. Ribs are mainly bone and cartilage with only a small amount of muscle.

That's normal. You look fine, please don't feel self-conscious.

I'm sorry people are telling you that! When your really slim its normal that the ribs will be more visible, don't worry about it and don't let others comments get to you.
You aren't at a very low weight for your height (although I don't think you should lose any more) so forget about what people are saying (most are just jealous or prefer to see you the way you used to look, we don't like change as a rule )

To be honest I think its just your build. My ribs, collar bone really protrude and I'm a rather high weight at the minute. Some folk just have a naturally wider set frame. You look great btw!

Congratulations on your great weight loss!

You dont look bad, and if you don't mind me saying, the problem you have is not your ribs (your skeletal structure looks perfectly normal) - its the fact that your abdominal muscles arent "large" enough. (pardon my french but english is not my mother tongue, I do not mean to be rude)

if you need some tips, here's some excercises that will help you gain abdominal muscles. That way, the "abs" will connect more (or appear more connected) with your ribcage, giving the ribs less of the protruded look that you say you have.

You will need to gain abdominal and torso muscle....and ofcourse be sure to excercise the rest - your whole body. But this you know already just find any type of excercise that you enjoy, which gets your heart rate up

I highly recommend doing this routine twice a week, with rest days inbetween: Abdominal muscle routine - Don't mind the bodybuilder look. This guy knows what he's talking about, he's won Mr. Universe 3 times.

Combine that with the Dumbbell Pullover excercise - but don't do this the same day as the sit up routine cause it will hurt and you might get injured. Or you could just go light weight: Dumbbell Pullover

The first routine works all of your abdominal muscles in some way. Its damn hard the first 3-5 times you do it, so dont be discouraged if you cant complete it the way Calum does.
Take breaks as much as you need, but dont relax too much, its supposed to be a workout - just set yourself the goal to complete the whole routine.
Notice how you improve your strength every time you come back to do the routine again!

As for the pain you will experience when working abdominal muscles. You will feel it, but you have had the (great) discipline to lose 50 lbs (!) - a little pain wont be anything compared to that.

here are some images to show the muscles youre working. https://fitnessonfiredotnet.files.wordpress.com/2014/05/st-dumbell-pullovers.png

Sorry for the wall of text, but I like explaining when I suggest things. Hope this helps

They're jelly. Spare skin aside, mine looks like that at what I consider best for me. The scale considers me to still be overweight then and I can't take that seriously so I go by whether losing or gaining would make me feel better physically and call it good.
