Virabhadrasana III (Warrior III Pose) is indeed a fundamental yoga pose that targets the muscles of the thighs and glutes, emphasizing balance and strength. For those who find maintaining balance challenging, spreading the arms to the sides, like airplane wings, can provide additional stability. For a more advanced variation, extending the arms forward without touching them together increases the challenge by shifting the center of gravity, requiring more core engagement and focus. Both variations enhance concentration, coordination, and muscular control.
