Start by laying on your back. Bend your knees to get your feet positioned close to your glutes, hip-width apart from each other.
Hold one of your legs up by pulling it towards yourself with both of your hands. Make sure to keep your back straight as you perform this exercise.
Push down on the ground with the remaining foot to lift your glutes and lower back off the ground. When your quadriceps align with your torso, squeeze your glutes and hold that position for the required time.
Slowly lower your body and get ready to repeat the motion on the remaining leg to complete a set.
