Basically our butt is made up of both fat and muscle; you need to use cardio and strength-training moves to target your butt.
We know that, high-intensity cardio exercise burns more calories and will keep your metabolism elevated throughout the day. Every 3,500 calories you burn will result in a 1-lb. fat loss. Perform 20 to 40 minutes of cardio exercise each day at a low to moderate intensity. Gradually increase the intensity of your workout once per week to start burning more calories.
Moreover, interval training allows you to perform at a very high intensity with rest periods built in to burn more calories than a steady-pace cardio session.
Select a form of cardio such as running or jumping rope, work at your highest intensity level for 30 to 90 seconds, work at a resting pace for 30 to 90 seconds, and repeat for a total of 20 minutes.
Now just try to perform two exercise those are proven toning the butt along with cardio exercises:
• Squats: Use high repetitions (12 to 15) without added weights during squats to avoid adding large, bulky muscles to your butt. To perform a standard squat, stand with your feet about 2 feet apart, shift your weight into your heels, keep your back straight, lower your body downward until your legs create a 90-degree angle, squeeze your butt muscles and stand back up. A side squat can be performed using a stair or aerobic step. Stand with your left side facing the step, place your left foot on top of the step, rock your weight into your heels and perform a squat. Switch legs and perform the same number of squats with the right leg elevated.
• Lunges: Lunges can be performed several ways to tone your glute muscles and shrink your butt--a forward lunge is the most popular and basic form. Stand with your feet together, place your hands on your hips for additional balance, step 2 feet forward with your right leg, bend your right knee to lunge, roll onto the toes of your left foot, continue lunging your hips down toward the floor until both of your legs create a 90-degree angle, hold for one second, push off with your right foot and return to the starting position. Perform between 12 and 15 repetitions with each leg. You can also perform lunges by stepping your leg to the side of the body or stepping behind. Changing directions helps to challenge your muscles.
Perform those two exercises with care. Hope so you would get tone butt.
