The side plank is an effective core exercise that targets the obliques, shoulders, and hips. By holding your body in a straight line on one side, you engage multiple muscle groups, improving core strength and stability.

1. Lie on your side with your legs extended and stacked on top of each other.
2. Place your lower elbow directly under your shoulder, forearm perpendicular to your body.
3. Engage your core and lift your hips off the ground, forming a straight line from your head to your feet.
4. Hold the position, keeping your body in a straight line, and then lower your hips back to the starting position.
