arms overhead full sit-up (male)

Lie flat on your back with your knees bent and feet flat on the ground.

Extend your arms overhead, keeping them straight.

Engaging your abs, slowly lift your upper body off the ground, curling forward until your torso is upright.

Pause for a moment at the top, then slowly lower your upper body back down to the starting position.

Repeat for the desired number of repetitions.
