If you’re not seeing results in the gym, there are a lot of things you can tweak: your diet, your exercise schedule, and the types of workouts you do, to name a few. But genetics is also a big factor. We’ve all had that thought on bad days: Maybe I’m just not cut out to succeed at this.
Height is considered ~80% heritable, but malnourishment and/or disease can stunt your growth. If you’re really serious about addressing your height, limb-lengthening operations (cosmetic surgery) are a reality. But tot only are they ridiculously expensive, but they also involve having your legs broken! To lengthen limbs, the bones are broken to be spread so the body fills the gap by healing. Anti-inflammatory painkillers can’t be prescribed because they might inhibit bone growth. At a rate something like a millimeter a day, the apparatus is tweaked daily. Some have achieved 6 inches, but most seem to be 2-3 inches. Surgery would require someone like me to be off blood thinners, so far less likely that anyone will want to do the surgery for you.
All that said, for me part of the process has been about accepting what I can not change.
