And by saying more traditional, you post a pic of 2003? Show me pre-1993 pics where everyone is posing like Ronnie, then I will concede that to you.
this has always been the traditional way.

Abdominals and Thighs (see Figure 7)
Standing face front to the judges, the competitor will
place both arms behind the head
and will place one leg
forward. He will then contract the abdominal muscles by
55
“crunching” the trunk slightly forward.
At the same time,
he will contract the thigh muscles of the forward leg.The judge will survey the abdominal and thigh muscles,
and then conclude with the head-to-foot examination.
