One really effective work out to get that visible definition on your lower back, butts and hamstrings is none other than the straight leg dead lifts exercise. Find yourself a barbell in a gym or purchase one for yourself. Hold it with both your arms. Make sure that you have an overhand grip over it. Now rise up to come back to a standing position, while maintaining a shoulder length distance between your arms and a shoulder length distance between your legs.

Lock the position of your legs in that shoulder length distance to each other. Now start bending forward from the position of your waist, until your complete upper body is exactly parallel to the surface of the floor. Make sure that you maintain a straight posture at your back. Ensure that your eyes are looking straight ahead of you. While you are doing this, the position of the barbell must be ahead of you, at arms length, that is to say it must be perpendicularly below you.

Continue to look straight ahead of you. Maintain that straight posture of your back as you get back to your starting position. While getting back to your starting position, make sure that you are relying on the muscles at the back of your leg for that reverse body movement. Again it is a must to maintain a straight back during this movement and not a curled one or a hunched one, as a non-straight posture of the back during this movement could inadvertently result in serious back muscle injury. This is the reason; it is recommended that you look straight ahead of you, because looking straight ahead enables you to maintain the straight posture of your back.

Another very important leg exercise is the lying or seated leg curl exercise. To work out areas like your hamstrings more effectively, you will have to find yourself a hamstring curl machine at a local gym or buy yourself one. The hamstring machine that you choose to purchase could be a seated machine, or it could alternatively be a lying down machine. If you have purchased a lying down machine, lie down flat on your stomach on the seat of the machine. Hook your feet to the roller pad near your feet, with the help of your heels and the back of your ankles. 

Ensure that your legs are straight and completely stretches out. This will in turn ensure that your feet are locked to the roller pad with the help of your ankles. Keep a firm grip on the handles adjoining the seat on either side of your body. Now ensuring that your body stays firmly stuck to the seat and doesn't wiggle or shift or gets lifted off the seat at any point owing to the weights being pulled up by your feet locked at the lower pad, gradually raise your feet, until your hams are fully curled and contracted. Then gradually reverse your movement and release you're the curl of your hams to come back to rest position. 

Doing these exercises will really help you out with burning all of those fat deposits in and around your thigh and hip areas. These exercises will develop, tone, build, strengthen and add definition to all the muscles in your lower body. This way you can be the proud of the sexiest pair of thighs. Remember to balance out your exercise regimen by coupling these lower body exercises with other upper body workouts. Finally, you can keep the results long-lasting by having a continuous, consistent and lifelong healthy fitness and diet regime.
