1 - Lie flat on your back on the floor and hold a barbell with a slightly wider than shoulder-width overhand grip, pressing it directly above your chest with arms fully extended.
2 - Keep your arms locked out and the barbell stable throughout the entire movement — this is your fixed position.
3 - Raise both legs together until they are perpendicular to the floor (90 degrees), keeping them straight and together.
4 - Slowly lower your legs to the right side, bringing them as close to the floor as possible without touching it, while keeping your core engaged and hips from rolling excessively.
5 - Raise your legs back to the center (vertical position) in a controlled manner.
6 - Lower your legs to the left side in the same controlled fashion, mirroring the movement on the opposite side.
7 - Return to center and repeat for the desired number of repetitions, alternating sides each rep.
