This exercise can be done with a dumbbell, kettlebell, plate, or medicine ball. If you aren’t ready to add weight yet, doing it without weight is fine too.

• Grab a weight (medicine ball, kettlebell, dumbbell, or plate).
• Secure your feet on a decline bench and lie back about halfway.
• Keep your abs tight and rotate your torso side to side. Make sure you’re rotating your torso using your abs, and not only moving your arms side to side.
• The closer you hold the weight to you, the less challenging the exercise will be. The further away you hold the weight from you, the more challenging it will be.
• You can count reps however you’d like. You can count 1 rep as rotating to each side, or you can count each rotation as 1 rep.
