Strengthening the glutes is not only good for your backside appearance. Your glutes provide you with the ability to walk, run, jump and twist, so increasing the strength of your glutes increases your speed and agility for participation in sports and everyday activities.
Keep your leg at a perfect 90 degree angle forcing the hamstrings to work to maintain the pose. This way you also get a great hamstring workout.
Keep your core tight, your back and neck straight in a natural position, and your face down to avoid straining the neck. Don't let your back arch when you lift the leg.

If you want more resistance, you can use ankle weights or hold a dumbbell with your knee crease, although holding a dumbbell might feel uncomfortable with heavier weights.
