Instructions
Advanced Kettlebell Windmill
Clean and press a kettlebell overhead with one arm.
Keeping the kettlebell locked out at all times, push your butt out in the direction of the locked out kettlebell. Keep the non-working arm behind your back and turn your feet out at a forty-five degree angle from the arm with the kettlebell.
Lower yourself as far as possible.
Pause for a second and reverse the motion back to the starting position.
Jackknife Sit-Up
Lie flat on the floor (or exercise mat) on your back with your arms extended straight back behind your head and your legs extended also. This will be your starting position.
As you exhale, bend at the waist while simultaneously raising your legs and arms to meet in a jackknife position. Tip: The legs should be extended and lifted at approximately a 35-45 degree angle from the floor and the arms should be extended and parallel to your legs. The upper torso should be off the floor.
While inhaling, lower your arms and legs back to the starting position.
Repeat for the recommended amount of repetitions.
Verdict
Both exercises target the abdominals. Advanced Kettlebell Windmill is a intermediate exercise using kettlebells, while Jackknife Sit-Up is beginner and uses bodyweight. Choose Jackknife Sit-Up if you're looking for a more accessible option, or Advanced Kettlebell Windmill for a greater challenge. Jackknife Sit-Up is a compound movement working multiple joints, making it better for overall strength. Advanced Kettlebell Windmill isolates the target muscle for focused development.
