Lie on your back with your knees bent and feet flat on the floor. Place your arms by your sides with your palms facing down.
Engage your glutes and core muscles by squeezing them tight.
Press your feet into the floor and lift your hips up towards the ceiling.

Continue to lift until your body forms a straight line from your shoulders to your knees.
Pause for a moment at the top of the movement, squeezing your glutes and core muscles even tighter.
Slowly lower your hips back down to the starting position.
Repeat for the desired number of repetitions.
