Where do you want to grow? In your daily routine? In your flexibility? In your strength? In your balance? In your ability to recover? Want a single work-out that achieves all of it? Yoga is your answer. Adding a yoga practice to your current practice, whatever that may be (yes, working at a desk is a practice), will give you the tools to internalize and build the mental and physical skills to achieve positive growth in your daily life and routine off of the yoga mat.
Yoga is a life long practice. With this in mind, understand that when you start yoga, your "ability" to perform yoga is exactly where it needs to be. There is no such thing as perfection in yoga. You do not need to be "bendy" to do yoga. What is required from you is an effort to build your patience with yourself, your body, and your mind. Through a practice in yoga, you will naturally develop an all over patience, giving you an ability to better handle situations that may present themselves, like a Colorado traffic jam, with a brighter, more open attitude.
