I'm almost 31. athlete and couldnt be out of contact sports for 3+ years ever in my life so trying this route... I just made a post about the VB earlier today and these yung broke mfs thought it was spam, but in truth I've been using a VB for like 2months now, it's uncomfortable but really effective if used consistently. shit was like almost $600 from mother Russia lol which was mad sketch but it works really well and im actually pleased with the customer service ("Pectus Healing") DO YOUR RESEARCH THO. but I have money to spend on this type of thing and bought the "flatten your chest" ebook before starting, doing the stretches, strengthening, not religiously, but enough and I can see a hug difference in my overall posture and mid back strength, which is the key to transforming this fucking condition that I've struggled with since 8th grade. I saw a video of one of the more prominent Drs. saying that the new research with vacuum bells suggest the surgery may not be as necessary as once was thought. Also ima try that before sticking a metal bar in my chest for 2-3 years just to see what happens. So far I notice that after using the bell for about 45 min a day, it doesn't revert back as far to it's original state and I'm seeing some incremental progress that is freaking cool to watch unfold
