A common misconception for people that are not all that familiar with how yogic practices work is that you can just see pictures of a few poses and start practicing them without really worrying about anything else. The truth of the situation is that yoga can be easy if you know how it works, but if you are a complete newbie then you might not know the correct ways in which these poses and stretches need to be achieved and subsequently maintained for a short period of time.
If you do yoga incorrectly, it is highly possible that you would injure yourself. Pulling a muscle is quite common among yoga neophytes, and in some cases joint injuries also occur. A trained professional can help prevent such things from happening. They have the expertise to know how our bodies might try to take shortcuts while adopting yoga poses. They use this expertise to keep your body steady and prevent jerks and sudden movements that can result in injury. They can also fix tiny imperfections in your posture during each pose. Holding an incorrect pose can slowly result in you feeling pain in a few areas here and there, and while this might not initially seem like much over time it can lead to some serious drawbacks such as chronic joint pain or lower back pain. Once an injury is attained, it will be quite difficult for you to get back to practicing yoga which is why you need to be careful.
