      Things genetic testing is currently good at: - rare genetic diseases - typing cancers - antenatal screening Things genetic testing is mostly useless at: - ancestry testing - general population screening - exercise/fitness plans - most other things

      Some of these are less ridiculous than others. Testing your ancestry, for example, makes a bit of sense even though it's hard to do

      But identifying specific genes that would make a difference to what exercises you should be doing is far beyond the current scope of genetic tests and doesn't make much sense anyway

      Like this, for example. Total nonsense. How in the world would variations on a few genes make a difference to your exercise regimen?pic.twitter.com/CQgWUTedCU

      As far as I know, the tests are based on what is essentially very primitive knowledge. So we have associated certain genes with the ability to put on muscle, but they only predict a tiny fraction of a person's actual muscle mass

      So there's a genetic component to muscle mass, but it's a small percentage. And we may not have identified all the genes anyway. The genetic tests picks up a few allele pairings that have been correlated with increased muscle mass and tell you that's predictive

          Definitely. Also, that their tests have any predictive power
