Plank hold - kneeling.

How to:

Start by kneeling on the ground with your knees hip-width apart and lower your forearms onto the ground, elbows directly below your shoulders.
Extend your legs behind you, keeping your toes tucked under and resting on the balls of your feet.
Engage your core muscles by drawing your navel toward your spine and squeezing your glutes.
Maintain a straight line from your head to your knees, avoiding any sagging or arching in your back.
Keep your gaze down, maintaining a neutral neck position.
Hold this position, keeping your core and glutes engaged, for the desired duration.

Coaching cues:

Focus on maintaining a strong and stable core throughout the exercise.
Keep your shoulders relaxed and away from your ears, allowing your forearms to support your weight.
Imagine a straight line from your head to your knees and actively engage your abdominal muscles to prevent any arching or sagging in your back.
