The 12 Best Oblique Exercises For a Stronger Core

If this oblique exercise is too difficult, try it without a weight. You can also use a kettlebell or medicine ball instead of a dumbbell.

• Sit on the floor with your knees bent and your heels resting on the floor. Lean back slightly without rounding your spine, and hold a dumbbell horizontally with both hands in front of your chest.
• Keeping your core engaged, twist your upper body to the right, being careful not to move your hips or knees.
• Return to the center, then twist to the opposite side. That's one rep.
