I recently discovered I had a small separation in my upper abdominal muscles. Its embarrassing to admit but it was basically caused by gaining weight, then loosing weight and doing exercises too fast to compensate. I'm told this is a common thing, but who cares when you're the one feeling the shame. I ordered this to help with abdominal compression while at work. It's comfy, breathes and straightens my posture. I sometimes use it for sleeping in too because it really is that comfortable. I still have ways to go with weight loss but this really has helped.
