Ways to Lift Your Breasts:

 Right Bra Size: Firstly, it is very important to get the size of your bra right. Squeezing into a small bra may cause injury to breast tissue, poor posture or even back pain. Also, right bra size can give your breasts a natural lift.

Exercise: Though the breasts are mainly composed of fat, the entire mass sits on top of a muscle called pectoral. Exercise can build up the muscle, and prevent drooping breasts or sagging. Here are few exercises you can do to keep your breasts firm:

Push-ups: Practice around 10 push-ups a day to strengthen your pectoral muscles. The right way to do it is by starting on your fours, with feet close together and palms slightly wider than your shoulders. Your body should form a straight line from head to toe. Lower down until your chest almost touches the floor. Keep your upper arms at a 45 degree angle to your torso. Pause, then repeat. You should see results in a month or two.

Weight Lifting: Weight lifting is a great way to build up your pectoral muscle. You can try bench pressing or the dumbbell fly. To start off with, try a simple balance ball exercise you can do at the gym or at home. Use a balance ball to support your weight under your upper back and extend your legs out in a 90 degree angle. Start with a free weight in each hand with your hands rested on the ground at your sides. Bring your arms up into a 90 degree angle and hold the position for a few seconds. As soon as you can no longer handle the position, drop the weights back down to your sides, take a few seconds to rest and go back into the same motion.

Aloe Vera Gel: Aloe Vera is known to have natural skin tightening properties. Massaging with Aloe Vera Gel exercises the muscles and tones the breasts. You can also try almond oil, as it increases blood circulation.

Nutrition: The muscles will become tight if you fulfill the protein requirement of the muscles. Your body requires essential nutrients such as vitamins, calcium and minerals. These can be found in foods like tomatoes, cabbage, cauliflower, broccoli, carrot, meat etc. But along with this you need to reduce the intake of caffeine and also stop smoking.

Swimming: Just spending about half an hour in the pool can do wonders for your breasts! Swimming tightens the muscles responsible for holding your breasts. Swimming can help you burn fat and build muscle in your upper body, hence helps you lift your breasts and keep them firm.

Try out natural hair masks the next time you want to give your hair a deep treatment.

Treating your hair to a deep, nourishing mask every few weeks will make the world of difference. Women have been looking after their locks for decades - way before famous brands were around - so what did they use to use to give wonderful shine and soft-to-touch finish?

There are an astonishing amount of items in your kitchen which are great to use on your tresses. One which may surprise you is the banana, which is high in potassium and vitamins A, C and E.
Pop the mushy filling into a bowl or food processor and mix into a smooth paste. You want to make sure it's lump free as any small bits may prove tricky to rinse out.

Once easy to handle simply apply it to your hair and cover with a shower cap or plastic bag to stop the dripping. Or, if you wanted to really stimulate your roots to absorb extra nutrients, use your hair dryer after around 20 minutes to allow the banana to set.
Then all you have to do is rinse out the fragrant mixture, using a fine-toothed comb if needed as well as your regular shampoo.
If dry hair is your problem you may be brave enough to try out the next option.

Mayonnaise is a cheap, easy to purchase beauty treatment for your dehydrated locks. The gloopy white mixture is packed full of oil, which is guaranteed to add an extra shine and moisture to your hair. You don't need to go out and buy a whole new jar - a little amount will go a long way for this process.

Pop a small dollop of mayonnaise onto your hand and work it through your hair from roots to the tips. If the eggy smell is too much for you add a drop of scented oil to the mixture before applying.

You can leave this on for up to an hour to ensure your hair soaks up the oil before rinsing out thoroughly and shampooing.
Not all old-fashioned hair masks are made up of squidgy ingredients. One suggestion aimed at getting rid of dandruff is lemon and olive oil. Make sure your oil is plain - a flavoured one won't leave the nicest of smells!

All you need to do is squeeze two table spoons of fresh lemon juice into a small bowl with the same amount of olive oil and water. Mix thoroughly and rub into your hair, wrapping a warm damp towel over your hair to make sure no excess liquid evaporates. The good thing about this method is that it can be done once or twice a week as it's easy to make, apply and doesn't leave you with banana or mayonnaise smeared hands.

The maxim "He knows me better than I know myself"? Well, it probably doesn't hold true when it comes to pleasure centers. If you're like many women, you have had a long-term relationship with a vibrator and, with concentration, can get the deed done during a commercial break—without even muting the TV—if you so choose.

All joking aside, self-pleasure is important because it "lets you take control of your satisfaction," says Charlie Glickman, Ph.D., a sexuality educator. "It also gives you room to try new things without stressing about a partner's expectations." Add to that: Masturbation is a pressure release, a natural sleeping pill, and a plain old-fashioned good time (as if we needed to sell you on it).

Still, even if you and your vagina are so in sync you finish each other's sentences, your sex life with yourself, like with any long-term partner, has room for improvement.

So put away your vibrator. Not forever—just for a few minutes. Because to improve your self-loving skills, the best place to start is the mind. "Seduce yourself," suggests sex coach Amy Levine, founder of IgniteYourPleasure.com. That doesn't mean making a rose-petal path to your bed, but some low-maintenance pampering can get you in the mood. Levine recommends playing soft music and lighting candles. Porn works too, if that's your thing. So does eyes-closed fantasizing. Says sexuality educator Timaree Schmit, Ph.D.: "Envision a situation that turns you on, and let it fully develop. Never judge yourself or say you should be thinking about something or someone differently. There's no so-called thought police."

Once you've worked yourself into a mental lather, focus on your body. Levine suggests starting with a slow full-body self-massage. You already know the one or two spots that can send you over the edge, but now is your chance to discover untapped sources of pleasure. Levine says to pay special attention to your neck, the back of your knees, your thighs, and your perineum, which is the stretch of skin between your vagina and anal opening.

After your massage, avoid falling into your time-worn getting-off pattern. Switch up your position, suggests Levine: If you always masturbate while lying on your back, try it on all fours, or sitting in a comfortable chair, or even standing, bent over a table or the bed. Try kneeling as if you're straddling your partner.

Variety is key to your sex life, so why shouldn't that extend to your self-love life? If you need more convincing, know this: By masturbating the same way every time, you might have more difficulty getting off when you're with a partner. So stay flexible.

Speaking of which, consider taking a yoga class and then getting it on with yourself as soon as you arrive home, says Levine. "The breath work and the flow of the poses allow us to be in the moment and out of our head," she says. In other words, yoga can diminish all those thoughts of your boss, your bank account, or whatever other worries might distract you.

Now, getting back to your vibrator. If yours is a trusty rabbit style, it might be time to introduce vibrator 2.0. Perhaps something that hits the doubted-by-scientists-but-not-by-women G-spot? (A rabbit is tailored to the clitoris.) "Look for something that has a curve," suggests Glickman. "Stronger vibrations, or ridges or bumps, often help too."

Glickman recommends using a G-spot wand that's waterproof, like the Good Vibrations Silky G Waterproof G Spot Vibrator. Draw a bath, climb in, and go to town. Aim the toy's curve toward your navel when you insert it—the G-spot is a couple of inches inside the vagina, on the front wall. "Try to find an area the size of a dime or a nickel that feels raised, or ridged, or firmer than the tissue around it," says Glickman. "It's often easier to find when you're turned on, because it swells."

Don't feel like embarking on The Great G-Spot Hunt? No problem, says Leigh, who is all for clitoral focus. "There's increasing pressure that you should be able to get off from G-spot stimulation," she says. "But just do what feels best to you." She recommends clitoris-specific egg-shaped vibrators for easy use and storage.

"But the Cadillac of vibrators is still the Hitachi wand," she says of the massage device that resembles a giant microphone. "It's huge. It often requires an electrical outlet and can be noisy as all get-out. But if nothing else will get the job done, this will."

Of course, toys aren't everyone's cup of tea. And that's fine. All that matters is that you feel good. And if you're playing sexy music, massaging yourself, and writhing in a chair while feeling good, all the better.
