Have you ever wondered what your handshake says about you? Your handshake is like your business card. It conveys your confidence, credibility and influence without sharing a single word. Studies have shown this one simple gesture can enhance a social situation and make a positive impact on others.

In our culture a handshake accompanies almost every introduction and initiates many conversations. It sets the tone for new relationships by signaling others of your integrity. People often admit to judging others based on this small gesture.

Because of this, The Journal of Personality and Social Psychology encourages everyone to pay attention to their handshake as it’s found significant consistencies in a firm handshake and a positive first impression.

Make a great first impression by considering your handshake and what it says about you. And avoid these eight types of handshakes that will hurt your influence with others:

1. Dead Fish: Also known as the limp noodle, this handshake conveys weakness and uncertainty. Don’t use this handshake even when tempted to be gentle with a person due to age or gender.

2. Hand Crusher: This type of handshake - a squeeze with constant force - diminishes trust others are willing to place in you. It sends the message you’re trying too hard, and people will likely question what you say after that.

3. Long Lingerer: Handshakes should be no more than two seconds in length. Anything longer begins to cross personal boundaries and feels like a desperate invasion of space.

4. Hip Hipster: Fist bumps and fancy handshakes have their place - with friends and family. They have no business in the workplace. They reflect a lack of awareness and a need to be revered as cool, not credible.

5. Brush Off: When shaking someone’s hand, be deliberate with your eye contact and don’t rush the exchange to avoid risking that person feeling brushed off.

6. Wet Weasel: We all get nervous and have anxiety before big meetings or introductions. It’s natural. But you probably already know if you’re likely to have unusually wet palms before the introduction. If so, then carry a handkerchief in your pocket to use just before the introduction. You can also wash your hands with cold water to help keep them cool under pressure.

7. Hand Hugger: Shaking hands with someone who uses both of theirs to embrace the entire hand is fine for a personal situation with friends and family, but it’s out of place in a professional setting.

8. Shugger: The shug is best known as a handshake that pulls the receiver closer to you physically, almost as if you were going to hug them. It forces them to come closer as your hand stays closely tucked into your body. While this type of handshake is common among friendly colleagues and peers, it sends a message of favoritism to those witnessing it. Remember, your handshake conveys a message to everyone, not just the person with whose hand you’re shaking.

Now that you know what to avoid, how do you perfect your handshake? Start by seeking feedback on yours. Ask someone you trust to help identify areas of opportunity. Then practice it on others to solicit feedback and more guidance until you’ve mastered it.

Some keys to the perfect handshake include:

1. Anticipate the Handshake: Ensure your hand is free, out of your pocket and not holding onto any items. Switching hands to shake is distracting and awkward.

2. Use Your Right Hand: Even if you’re a leftie, our culture dictates right-handed handshakes as key.

3. Maintain a Strong, Confident Posture: Remain upright and refrain from leaning. If necessary, then take a step toward the person with whom you're greeting. If you’re seated upon meeting someone, stand up before shaking that person’s hand. This signifies respect to the person you’re meeting.

4. Make Intentional Eye Contact as You Greet the Other Person: Once your hand makes a connection, ensure your eyes connect, too. Use a kind greeting such as “nice to meet you” or “great to see you again.” Incorporate their name with your greeting to help better solidify your introduction. This interaction trifecta will warm up anyone with whom you connect.

5. Remain Firm Throughout the Handshake: Grasp the other person’s hand with a firm grip without squeezing. Maintain the grip for two seconds before releasing. Don’t allow your hand to fall limp upon the initial grip.

6. Shake from Your Elbow, Not Your Wrist: Two or three pumps will do. Any more, and your handshake partner will begin to feel uncomfortable.

You want to be so confident in your handshake style that it’s second nature. Seeking feedback and frequent practice will help solidify your good habits so you can concentrate more on meeting the person and less on the impression you’re making. The more comfortable you become, the more confidence you’ll convey.
