Lie flat on your back with your legs extended and your arms by your sides. Bend your knees and place your feet flat on the ground, hip-width apart. Lift your hips off the ground, engaging your glutes and hamstrings. Slowly curl your legs towards your glutes, keeping your hips lifted. Pause for a moment at the top, then slowly extend your legs back to the starting position. Lower your hips back down to the ground. Repeat for the desired number of repetitions.
