When somebody says that they practice yoga, it could mean any number of things. They could struggle through a beginner class once a week, go on those scary-looking machines in reformer pilates, or spend half their time going on retreats where they make you 'practice gratitude' and eat raw vegan. However, it's precisely because there are so many different types and lifestyles to go along with them that it's so popular. That, and it is one of those things you can use to feel better about yourself and better than other people if you're that way inclined. It's no surprise that it has also inspired plenty of memes as let's be real, there is quite a lot that can be funny about taking a lot of deep breaths and twisting yourself into increasingly complicated shapes. Yoga has many physical and mental benefits, and this can be counted as one of them.
