Scenario: Leo has recently joined a Capoeira class. During his session, he watches his instructor intensely as they demonstrate a complex spinning kick called the Meia Lua de Compasso. He mentally rehearses the step-by-step sequence of twisting his hips and placing his hands flat on the floor. He then pauses to consider whether his hamstring flexibility and core strength are sufficient to execute such a deep, low spin. Leo is determined to practice this kick diligently because he wants to earn his first graded belt at the upcoming ceremony.
