Before you go, consider this really atrocious circus and biomechanics-themed riddle:
"I'm a muscle, strong and wide, known for power and might. In aerial acrobatics, I play a crucial role, soaring to great heights.
I'm located in the back, spanning diagonally from left to right with grace. Contracting and relaxing, I control movements in aerial space.
I aid in pulling and rotating, with force that's hard to ignore, In straps, rope, and hoop, I'm a muscle to explore.
Guess who I am, this aerial acrobatics ace? This powerhouse that helps aerialists move through space."
