While there is no way to specifically target your hips with cardio, this HIIT workout will help you burn fat everywhere on your body, which may also result in smaller hips. High Knees From a standing position, begin running in place, pumping your arms at your sides. Bring your knees up as high as you can. Keep your chest up and back straight. Continue for 45 seconds. Complete 3 sets. Superman Crunch Beginning in high plank position, extend your left arm forward while also lifting your right leg off the ground. Lift your leg until you feel tension in your glutes. Engaging your abs, lower your leg and arm without touching the ground. Bend at the elbow and knee and bring them together under your torso. Extend them again until you feel tension in your glutes. Perform 10 reps, then switch sides. Complete 3 sets. Mountain Climbers Start on all fours with your arms fully extended beneath your shoulders, supporting your weight on your hands and toes. Your back should be flat. Bring your left knee to your chest, then quickly switch legs, driving your left leg back as you bring your right knee up to your chest. Repeat in a continuous motion for 30 seconds to a minute. Bicycles Lie on your back on a mat and place your hands behind your head so that your elbows are sticking out to the sides. Raise your legs so that they create a 45-degree angle with the floor. Engaging your abs, twist your torso as you bring your left elbow and right knee together at the center of your body. Lower your left elbow and straighten your right leg back to starting position, as you twist your torso in the opposite direction, this time bringing together your right elbow and left knee. Continue albernating for 10 to 12 reps. Complete 3 sets. Comando Folds Start in high plank position with your weight supported on your hands and toes, arms fully extended beneath your shoulders. Drop down onto your left forearm, followed by your right. Then, push back up into high plank position. Transfer your weight to your arms and jump your feet towards your hands. Jump back to starting position. Repeat the movements 10 times. Complete 3 sets. Plank Jacks Begin on all fours, placing your hands directly under your shoulders, supporting your weight on your toes. Your legs and arms should both be fully extended. Jump your feet apart, wider than hip distance, then jump them back together. Perform 3 sets of 10 reps. Plank Rotation Begin on a mat, lying on your side with your legs stacked. Prop yourself up on your elbow and bottom foot and engage your core as you fully extend your top arm toward the ceiling. Twisting through your core, bring the top arm through the space between your torso and the floor. Then, fully extend it toward the ceiling again. Complete 3 sets of 10 reps on each side. Squat Oblique Twist Stand with your feet a bit wider than shoulder-width apart, chest lifted, hands behind your head. Push your hips back as you squat down, keeping your weight in your heels. As you push back up out of the squat, drive your left knee towards you right elbow. Return to starting position and repeat the movement on the opposite side. Continue squatting and alternating sides for 10 to 12 reps. Complete 3 sets.
