Form tips
- Land softly on the balls of your feet with slightly bent knees to protect your joints from impact.
- Keep your core engaged throughout the movement to maintain a tall, upright posture.
- Maintain a steady, rhythmic breathing pattern, inhaling as your arms go up and exhaling as they come down.
Common mistakes
- Landing flat-footed or with locked knees, which increases joint stress on the ankles, knees, and hips.
- Flailing the arms loosely instead of moving them with control and tension.
- Allowing the knees to collapse inward when jumping out and landing.
