Posture is key. Doing this will increase your over all confidence. Let's do a small exercise.
Start by facing the mirror and then turn 90 degrees to the right or left. You should have a perfect "side view" of yourself. Now look at the "ridge" that extends from your neck to the end of your shoulder. If you're wearing a shirt, look at the seam that extends from your neck to your sleeve. That seam or ridge on almost everyone will be slanted forward. Move your shoulders back until that ridge or seam is straight — going straight from your neck to your shoulder. That’s the optimal position for your shoulders. Remember that position and remind yourself to hold your shoulders there as often as possible.
Next, turn and look directly into the mirror, with your shoulders back, raise your chin up until it’s at a 90-degree angle with your neck. Your eyes should be looking dead-ahead now, straight into themselves in the mirror, or aiming straight at the horizon as if you were walking. Make the back of your neck as straight as possible with your back. Notice when you pull your head up like this with your shoulders back, your stomach naturally comes in, and your back naturally straightens up. This is what we want!
Next, look at your feet. They should be shoulder-width apart. Take note of which way your feet are pointing. They should be pointed straight ahead or slightly outward at the most. If they’re pointed inward or very far outward, this will cause posture problems and make you walk funny. Turn them straight ahead or at a slight outward angle and hold them there. If they continue to point in or out (especially when you sit down), it means that your calf muscles are too tight, and you need to stretch them or roll them with a foam roller.
Now, it’s time to walk. Hold the position you’re in — shoulders back, head up, back straight, stomach in, feet straight — and then slowly step in front of you. As you walk, you want to swing your shoulders. Not too far, because that’ll make you look ridiculous, but move your shoulders as you walk. This will create swagger and make you look more relaxed as you walk. It will probably feel weird looking straight up and ahead while you’re
walking, but this is good. You want to be able to look everybody in the eye as you walk by them.Finally, swing your arms slightly. If you don’t swing them, you look robotic. If you have them in your pockets, you’re either cold or a pussy. If you swing them too far, you look ridiculous. Just give them a slight swing… to go along with your swagger. There.
