Yes! You are a perfect candidate for yoga. Many people think that they need to be flexible to begin yoga, but that's a little bit like thinking that you need to be able to play tennis in order to take tennis lessons. Come as you are and you will find that yoga practice will help you become more flexible.
FLEXIBILITY NOT REQUIRED
On a physical level, yogic exercises strengthen, lengthen, and replenish muscle tissues, which helps to hold bones, and to align the whole body. Holding postures - burns fat and reduces cholesterol. Yogic breathing brings more oxygen to the heart and nourishes the whole system. The breath also aids in reducing toxin levels in the body by expelling unwanted stresses. Yoga’s greatest benefits are felt in the mind.
The word yoga, from the Sanskrit word yuj means to yoke or bind and is often interpreted as "union" or a method of discipline.
Yoga is not a religion. It is a philosophy that began in India an estimated 5,000 years ago. Yoga sometimes interweaves other philosophies such as Hinduism or Buddhism, but it is not necessary to study those paths in order to practice or study yoga. It is also not necessary to surrender your own religious beliefs to practice yoga.
All you really need to begin practicing yoga is your body, your mind, and a bit of curiosity. But it is also helpful to have a pair of sweat pants, leggings, or shorts, and a t-shirt that's not too baggy. No special footgear is required because you will be barefoot. It's nice to bring a towel to class with you. As your practice develops you might want to buy your own yoga mat, but most studios will have mats and other props available for you.
