1. Start in a standard plank position with your forearms on the ground and elbows aligned below the shoulders, and your body in a straight line from head to heels.
2. Engage your core by pulling your belly button towards your spine and tighten your glutes.
3. Lift your right foot off the ground, raising your leg until it is in line with your back, keeping it straight. Hold for 3 to 5 seconds.
4. Lower your right foot back to the starting plank position.
5. Now, lift your left foot off the ground and repeat the process.
6. Alternate raising each leg while maintaining a tight core and a neutral spine, without letting the hips sag or rotate.
7. Continue alternating legs for the duration of your set.
8. Remember to breathe normally throughout the exercise and keep your head and neck in a neutral position, eyes looking down at the ground.
Note: Ensure that your body does not sway side to side too much, and try to keep as much stability as possible through the core and pelvis through each leg raise.
