You are an athlete. Whether you compete or not, you invest time and energy into an athletic pursuit. As an active, fit, intelligent person, you understand the need for balance in your life, and balance in your exercise. There are so many ways to cross-train, and chances are you have given yoga a try. But, well, it's just so static. And foreign--not just in the use of Sanskrit terms, not just in its poetic, descriptive turns of phrase, but in the very traditions that shape it.
There are so many positives to a regular yoga practice, it does seem a shame to throw the baby out with the bath water. Rather, aspects of yoga can be extracted from their traditional setting, can be examined through the lens of exercise physiology, and can be applied to your training in the same goal-oriented fashion as intervals, plyometrics, and speed drills.
That is the idea behind Sport Yoga. While there is a lot of variety in how this approach can be realized in yoga class, the common thread is the idea that yoga can be prescribed to achieve a specific fitness goal, and--in the hands of an experienced instructor--can be shaped into a valuable tool to enhance and augment the other aspects of your fitness.
