Almost any kettlebell stomach exercise can light up the core muscles, but there are a few that really target the abs. The kettlebell straight arm sit is an excellent choice to hit your abs in a different way, requiring you to use a longer lever that can make the movement more challenging than simply sitting up. Another great kettlebell abs exercise is the V sit, which challenges your ability to stabilize the upper body while working the lower back muscles with a rotational motion that also helps strengthen the core.

The renegade row is another kettlebell abs workout that targets your shoulders and core. Start in a half-kneeling position, knees bent at 90-degree angles, right foot in front, and hold the kettlebell by the horn. With the left hand, circle the weight diagonally across the body to the outside of the left hip, and then up overhead as if forming a “halo” over your head. Slowly lower it back down, and repeat for 8 to 10 reps before reversing the direction and doing the same on the other side.

Kettlebell Core Crusher: Strengthen Your Stomach with Dynamic Exercises

Another great kettlebell abs workout that is less dynamic than some of the others is the kettlebell push up plank with a twist. Lie flat on the ground in a plank position, with one kettlebell held by your hands, handles up. Then, lift your left leg off the floor (you can keep the heels on the ground if you are a beginner), and twist your upper body from side to side.
