Using a kettlebell can be a great addition to your ab workouts, as it can help engage more muscle groups. In particular, the kettlebell swing is a very effective movement that can target your core muscles and also your shoulders, back and arms, says Duncan. She recommends starting off with a lighter weight and gradually increasing it as you master the movement.

The figure eight is one of the most challenging kettlebell exercises for your abs, but can be easily modified for beginners. Start by lying flat on the floor with a kettlebell in your hands, keeping the heel of your foot on the ground. Lean back, passing the kettlebell underneath your opposite leg then under the other leg – like weaving the bell into a figure 8. Repeat for 10 to 15 reps on each side.

Another advanced kettlebell exercise that is highly effective for your abs is the straight arm sit. With a suitably-sized kettlebell held in both hands, lie on the floor with your legs hip-width apart and keep your heels on the ground. Lean forward and grasp the kettlebell with one hand, then push your hips back and thrust them forward as you pass the weight laterally across your body, underneath your opposing leg. Keep your core tight as you swing it back down past the other knee, bringing it up to overhead before lowering back to your starting position.

Finally, the wood chop is a great kettlebell abs exercise that targets the obliques. Kneel on the floor in a half-kneeling position with your left knee planted in front and right leg bent at around 90 degrees, holding a lighter kettlebell with both hands low beside your left hip.
