The internal and external obliques are overlooked by most people who work out. In my case they are pertinent to my Pectus Carinatum workout. Most people can do sit ups and make their abs look good. For someone with Carinatum, doing sit ups alone will exaggerate the “V” shape of your chest. You want to increase your oblique workout to build the muscles under your pecs. Working out for Carinatum is an art and you must focus on building muscle where there is a void or depression in your body. In my case there are two sunken areas below my pecs.
Any twisting motion while you do sit-ups will work your obliques. This is the same for hanging leg raises with any twisting, side-to-side motion. There are literally dozens of different motions that will work these muscles. Get creative and or look up some oblique workouts on the internet.
