If you practice yoga at home without an instructor, you may first question if you're performing the postures correctly. It's important to remember from the start that our bodies as well as bone structures are all extremely diverse, so there's not just one 'correct' way to execute a posture. It's all about figuring out what works best for our individual bodies. The most important thing to remember is that yoga is not supposed to hurt - whether you practice at home on your own or in a workshop with an instructor. You will most likely feel different sensations than you are accustomed to, and you might just feel your tensed muscles, but if you feel any sort of “warning” discomfort, like sharpness or pinching, pay attention to your body and carefully come out of the posture.
