Attitude turn 1.5
Back attitude turn 1.5
Your stank ‘tude
Attitude is a term gymnastics borrowed from ballet (so if you want to pronounce it with a French accent as pretentiously as possible, by all means be my guest. It refers to the leg being raised up toward the mid-line of the body with the knee bent. When we use the term attitude in gymnastics we are typically referring to back attitude as default, but there are others.
If the full turn in back attitude is rare on beam, then the 1.5 turn is going to be exponentially rarer. Even at a D value, no one is touching that thing.
