Unfortunately, basic squats alone will not give you a butt like Jennifer Lopez, which is a shame. You need to add many more glute exercises into your routine in order to build that butt. Try incorporating the Romanian deadlifts and hip thrusts to give you the shape you desire. Target the glutes from all angles with these exercises.
Single-Leg Glute Bridge
Lie on your back with your knees bent and your feet flat on the floor. Extend one leg up to the ceiling and on your exhale squeeze your glutes and push your hips up as high as they can go. Pause for 2 seconds then lower to the floor and repeat 10 times per side. You can add weight for more impact.
Single-Leg Dead Lift
Stand on one foot and with your other leg bent in front of you, knee at hip height. Engage your glutes as you bend forward, hands reaching towards the ground and extend the bent leg straight behind you. Return to starting positing and repeat 12 times on each leg.
Sumo Squat
Stand each foot on step wider than shoulder-width apart, toes are slightly angled out. Take a kettlebell or dumbbell with both hands and squat down, hips back and knees in line with your toes and then come up and squeeze your glutes. Repeat 12 times.
