Although you cannot get a bigger butt instantly with one or two workout sessions, training consistently and giving your body enough recovery to heal and adapt will gradually increase the definition in your posterior. Your buttocks consist of the gluteus maximus -- the large muscle that gives your butt its round curve -- that can produce a powerful force to extend the hip when you stand up from a squat or sprint. With a kettlebell, dumbbell or barbell, you can perform the squat and deadlift exercises to help you strengthen and enlarge your buttocks.
Warm up your body to get your blood flowing and your heart pumping by doing light jogging or jump-rope exercises for four to six minutes. Perform dynamic stretches in your whole body to loosen up your joints and wake up your nervous system, such as leg swings, standing torso twists, arm circles and clockwork lunges. Draw a few deep breaths into your belly before you lift.
Perform deadlifts. Place a 24- to 40-pound kettlebell on the floor in front of you. Stand with your feet about hip-distance apart so that the kettlebell is between your big toes. Bend your torso forward at your hips with your knees slightly bent and your back flat, and grab the kettlebell with both hands. Exhale as you push your feet against the floor to quickly straighten your legs. Thrust your hips forward at the same time, bringing your torso upright and the kettlebell off the floor. Your arms should be hanging in front of you with the kettlebell hanging near your groin. Keep your shoulders away from your ears and your knees slightly bent. Inhale as you lower the weight back to the floor by hinging forward at your hips and bending your knees.
Hold a pair of dumbbells -- about 15 to 20 pounds each -- in each hand by your sides, and stand with your feet about shoulder-distance apart. Inhale as you squat down as low as you can until your buttocks are below the height of your knees. Keep your shoulders relaxed and your back straight. Do not lift your heels up. Exhale as you stand up without rounding your spine or hunching your shoulders. The exhalation will automatically tighten your abdominal muscles to help maintain your posture.
