You can add weight to this exercise by holding a dumbbell, kettlebell, medicine ball, or plate in front of your chest. The further away you hold the weight from you, the more challenging it will be.

• Lie on a decline bench with your feet secured.
• Use your abs to lift your head and back off the bench. As you sit up, rotate to either side, bringing your elbow to the opposite knee.
• While keeping your abs tight, lower your back and head onto the bench.
• Repeat the above steps of using your abs to lift your head and back off the bench, but this time rotate in the other direction.
• You can count reps however you’d like. You can count 1 rep as doing a sit up rotating to each side, or you can count each rotation as 1 rep.
