The 12 Best Oblique Exercises For a Stronger Core

Adding a hip dip makes side planks even harder and amps up the burn you feel in your obliques. Be sure to keep your chest open and try not to bend at the hips.

• Begin in an elbow plank on your left side with straight legs and your feet stacked. Place your right hand on your hip or extend it toward the ceiling. Make sure your feet, hips, and shoulders are all aligned.
• Inhale and lower your left hip a few inches toward the floor.
• Exhale and engage your left obliques to lift your hips and return to the starting position. That's one rep.
• After finishing a set on one side, repeat on the opposite side.
