Shaping 
              your butt muscles is high on the wish list when women start with 
              a personal trainer. Every woman wants a nice firm butt. The butt 
              area is however also the so called problem area for a lot of women. 
              Women carry a lot of fat deposits in this area because it serves 
              them during their childbearing years. Female bodies are not very 
              willing to give up these fat cells, so women really need to need 
              to choose the right exercises and workouts to trim and tone the 
              gluteus maximus!
A shapely bottom is a wonder to behold. Usually it is only seen 
              on a few privileged women. Well not anymore! Are you ready to transform 
              your sagging behind? Here are the top five exercises to kick start 
              your exercise program and literally get your butt in gear. You will 
              be bouncing quarters off it in no time!
The Squat 
The squat is the single best exercise for strengthening, toning 
              and shaping the thighs and butt. Not only does it tighten and tone 
              your rear but its the #1 overall exercise for building lean quality 
              muscle!
Stand holding a barbell resting across your upper traps and shoulders, 
              hands wider than shoulder-width apart. Place your feet slightly 
              wider than shoulder-width apart, feet angled slightly outward. Pull 
              your shoulders back slightly, contract your lower-back muscles, 
              take a deep breath and hold it. Looking straight ahead, slowly bend 
              at the knees, inclining your torso forward slightly and descending 
              under control until your thighs are just above parallel to the ground. 
              Don't bounce at the bottom, but don't stop either. Push through 
              your heels to drive yourself back up, contracting your gluteus muscles 
              (buttocks) strongly and exhaling as you pass the halfway point. 
              Take a deep breath and repeat. 

 
 
 
             
The Lunge 
The lunge is another very popular exercise for toning and firming 
              leg and butt muscles. Position your feet about shoulder width apart, 
              with your feet pointing straight ahead. Pick up a pair of dumbbells 
              or a barbell(you may want to do a set without dumbbells first to 
              learn the movement), bending at your knees to make sure you don't 
              strain your back. To begin the exercise, step your left foot forward, 
              keeping your forward leg centered over your ankle. Make sure your 
              knee doesn't go beyond your toes or you'll place extreme tension 
              on the tendons of your knee. To help maintain balance, remember 
              to push off with your heels and not your toes. When coming back 
              to the starting position, focus on straightening your knee and hip. 
              Stay focused on your front leg even if you feel tension in your 
              back leg. Think of your back leg as the balancer and your front 
              leg muscles as the primary mover. Work one leg at a time rather 
              than alternating between one leg and the other. 

 

 
One-Legged Cable Kickback 
Hook a leather cuff to a low cable pulley and then attach the cuff 
              to your ankle. Face the weight stack from a distance of about two 
              feet, grasping its steel frame for support. Keeping your knees and 
              hips bent slightly and your abs tight, contract your glutes (buttocks) 
              to slowly "kick" the working leg back in a semicircular 
              arc as high as it will comfortably go. At full extension, squeeze 
              your glutes for peak contraction. Bring your working leg forward, 
              resisting the pull of the cable until you reach the starting position. 
              After completing the desired number of reps, complete an identical 
              number using the opposite leg.

 

 
Gluteus Kickback
              Get on your hands and knees on the floor, knees bent at 90 degrees 
              so thighs are perpendicular to the floor. Keeping your head up, 
              lift your right leg back and up, maintaining your 90 degree knee 
              bend, until your foot is higher than your head or your thigh is 
              horizontally in line with your torso. Squeeze your right gluteus 
              and slowly lower your leg back to start position. Perform the same 
              with your left leg, and repeat. 
Hamstring Curl 
This is a great exercise for toning and firming the hamstring and 
              gluteus muscles. Lie face-down on a leg-curl machine and position 
              your Achilles' tendons below the padded lever with your knees off 
              the edge of the pad. To begin the exercise, keep your back flat 
              as you raise your feet toward your glutes (butt) in a deliberate 
              motion. Squeeze the muscles and lower your feet with a controlled 
              speed. Repeat.
