1. Start standing with feet hip-width apart in a boxer's stance: hands in loose fists held below the chin with the elbows to the side, creating a triangular shape with the forearms.
2. Step right foot back to a runner's lunge with hips square and hands still in boxer's stance.
3. Bring right knee into the chest and kick right foot forward. Simultaneously punch with the left arm, wrist parallel to the floor with a slight bend in the elbow. Keep shoulders relaxed and gaze forward.
4. Return left hand to boxer's stance and step right leg back into lunge.
5. Repeat four times then lift arms overhead into the traditional Warrior 1 posture. Breathe and hold here, then repeat on the left side.
