Side Plank Dips Side planks target your obliques and trim your waistline, and by adding in the extra dip you will be improving your muscle control and posture. Start on your right side body with your elbow to the ground and your feet stacked. Raise your hips off the mat into a side plank position. Pause at the top and lower your hips down towards the mat with control. Stop your hips right before they hit the ground and return back up to full side plank. Repeat slow and controlled for 30 seconds, then switch sides. Image Source: POPSUGAR Photography
