captains chair straight leg raise

Sit on the captain's chair with your back against the backrest and your forearms resting on the arm pads. Keep your upper body stable and your back straight. Engage your abs and lift your legs up in front of you, keeping them straight. Continue lifting until your legs are parallel to the ground or as high as you can comfortably go. Pause for a moment at the top, then slowly lower your legs back down to the starting position. Repeat for the desired number of repetitions.
