Posture is not only a body position but a dynamic pattern of habits, reflexes, and adaptive responses to anything that resist you to be more or less functional and upright like athletic challenges, gravity, abnormal anatomy, and some awkward working conditions.
When you lose the needed stability for a task or start tipping over, there would be postural reflexes to kick in and engage your muscles to pull you into an upright and functional position once more.
Posture is more than just the sum of those parts. It's far more than just a collection of stabilizing and correcting reflexes: "Posture is how we live". It's the shape of flexible container and the physical manifestation of our comfort zone.
Posture can be uptight or apathetic, sad or happy, or fearful or brave. The rewards and challenges when you try to change and correct your posture are not only musculoskeletal, but also a personal profound process.

Popular Bad Postures
Imagine a powerful, strong, and confident person standing in front of you. What do you think is the type of posture that person has? It is a person who is ready to take on the world. Know some of the bad postures that you may have and learn how you can correct them before it gets worse.
1. Hunchback
It is caused by sitting with bad posture, especially at an office doing computer work. When you sit hunched over a computer screen, your chest muscles are forced to tighten and cause excessive curvature on your upper back. In line with this, relieve the chest tightness by doing self-myofascial release and stretching.
This will also help you strengthen the upper back postural muscles. One of the best exercises is the upper back foam rolling.

2. Forward Head
The muscles in your neck will become tight, as well as the levator scapulae and upper trapezius. The solution is to practice appropriate head posture through head backward sliding. It is also important to keep your line of sight ahead.
Make sure you are not tilting your head in upward position when you slide your head back. After that, it is advisable to get a massage or you can use a massage ball against your upper back as it can be a great help for relieving tension around your neck.
3. Over-Pronated Feet
The common cause of over-pronated feet includes improper footwear, pregnancy, or repetitive pounding on hard surfaces. This will weaken the arch, which results to over-pronation and even flat feet. This posture can add stress to the foot and tighten your calf muscles. It is also able to rotate your knees internally.
Over-pronation usually results to Heel Spurs, Post-tib Tendonitis, Plantar Fasciitis, Bunions, and Metatarsalgia. If the arch was already fallen, the best solution is going to orthotics. If the arch is weak or still in the process of falling, it may help you in strengthening your arches to run or walk barefoot. However, make sure you would check with your orthotics before doing your first step.

4. Rounded Shoulders
The main cause of this bad posture is sitting for a long time, or when you use not balanced exercise routine that requires excessive pressing on the chest. This will force the chest muscles to tighten and thus, may be able to rotate forward the should internally. Posture muscles in your upper back may loosen or weaken.
The solution in this bad posture is the same with correcting your hunchback posture. Using a massage ball, relieve the chest tightness, and do some stretching, while also strengthening your postural muscles in the upper back.
5. Forward Hip Tilt
Determining a forward tilt is a tricky process, but tilting your pelvis forward as far as you can, is an effective method. If you realize that your natural hip tilt is not as far away from your exaggerated forward tilt, you have this bad posture.
Forward hip tilt is caused by not stretching and by sitting too much, leading to shorteniubng of hip flexors. Hip flexors is a group of muscles on your hips, which are pulling the knee upward. This posture prevents the butt muscles or glutes from activating and thus, forcing the hamstring muscles to become excessively tight and overworked. If you have tight hamstrings, the main cause of your forward hip tilt could be an anterior pelvic tilt and tight hip flexors.
The solution here is stretching your hip flexors using the static lunges like crescent lunge. You can activate your butt muscles through exercises like foam roll and glute bridges, and by stretching your hamstrings.
