Lie with your back flat on the floor with your knees bent, feet on the floor. If you struggle to keep your feet completely flat on the floor, you can be on your heels instead.
Grab a barbell, plate, medicine ball, two dumbbells or kettlebells, and extend your arms straight out in front of you.
Use your abs to sit up as much as you can. As you sit up, keep your arms extended over you. At the top of the sit-up, the weight should now be directly over your head.
Once you sit up as high as you can, slowly lower your upper body back to the floor, keeping your arms extended over you.
