hello everyone, i am about 6 ft 3 and weigh around 140lbs. Ive recently had a chest operation called "pectus exclavatum repair" search it on google, very popular. i have never really had any muscle on my chest neither fat. i have a slight dip and my chest and would like someway to lose that dip, gain a bit of muscle and be able to just look normal, it would be amazing if someone could get back to me on this, pleasee.
