Mistakes to avoid with side plank variations

Here are some common mistakes to avoid when performing side plank variations:

1. Letting your hips drop: Your body should form a straight line from head to heels. Dropping your hips reduces core activation and strains your lower back.

2. Neck misalignment: Avoid looking up or letting your head hang. Keep your neck in line with your spine for better posture and less strain.

3. Holding your breath: Engage your core, but do not forget to breathe. Holding your breath increases tension and can fatigue you faster.

4. Overarching or rounding the back: Keep your spine neutral. Overarching or slouching can lead to poor form and back discomfort.

5. Shoulder not stacked over elbow or hand: If your shoulder is not directly above your supporting elbow or wrist, you risk unnecessary pressure and potential injury to the joint.
