Do you think that 2x BW snatch is just for the genetically gifted or anyone could have it if he/she is still young and can dedicate his/her time to train a lot (with a good coach)?
Of course the possibility/probability is higher for people in lighter weight classes. My 56kg friend for example has already snatched 107kg (1.9x) and my 62kg friend, 100kg (1.6x). The last one also achieved that in just 2 years, which is pretty damn quick.
As I'm a 77kg lifter (BW 74kg) and already 27 years old, 154kg seems so far away from my current 75kg PR.... Not to mention that it would probably become a new national record (lol).
