Bend your knees at a 90-degree angle, keeping your feet together.
Slowly raise your top knee as high as you can without moving your pelvis or letting your bottom leg leave the floor, mimicking the opening of a clamshell.
Hold this position for a moment, ensuring your core is engaged and your hips are still.
Slowly lower your knee to the starting position, completing one repetition of the Side Lying Clam exercise.
Pro Tip
**Controlled Movement**: Avoid rushing through the movements. When you open and close your legs, it should be a slow, controlled movement. This will help to ensure that you are using your muscles, rather than momentum, to perform the exercise. **Avoid Hip Rotation**: Another common mistake is to roll the hip backwards while lifting the knee. To avoid this, keep your feet touching each other throughout the exercise and make sure your upper hip doesn't roll back. **Mindful Muscle Engagement**: Focus on the muscle you are trying to work, which is the gluteus medius in this case
