A side plank is a core exercise that targets the obliques and the glutes. Here are the steps to perform a side plank:
Lie on your right side with your legs straight and your feet stacked on top of each other.
Prop yourself up on your right elbow and forearm, making sure your elbow is directly under your shoulder and your forearm is parallel to the edge of the mat.
Engage your core and lift your hips off the floor, forming a straight line from your head to your heels.
Hold this position for as long as you can, keeping your body steady and your breathing smooth.
