The side plank is an excellent exercise for strengthening the oblique abdominal muscles, which don't get worked as much during ab exercises like crunches. You will hold your body on its side in a straight position supported only by one arm and the side of one foot. Strong obliques are useful as core stabilizers.

The side plank targets the obliques, glutes, hips, and shoulders. It enhances lateral core stability and strength, which are crucial for balance and rotational movements. To perform a side plank, lie on your side with your legs extended and stacked on top of each other. Prop yourself up on your elbow, ensuring your shoulder is directly above it.
