"Yog Prayogshala" translates to "Yoga Laboratory," suggesting a center dedicated to the exploration and practical application of yogic principles. While a specific, prominent "Yog Prayogshala" yoga center in Haldwani with extensive online information is not immediately apparent, the name itself implies a focus on a deeper, perhaps more experimental or research-oriented approach to yoga.

Such a center would likely offer a comprehensive range of traditional yoga practices, including various asanas (postures), pranayama (breathing techniques), and meditation. It might emphasize understanding the scientific and philosophical underpinnings of yoga, going beyond mere physical exercise. Courses could potentially include therapeutic yoga, advanced meditation techniques, and workshops exploring the mind-body connection in depth.

A "Yoga Prayogshala" would aim to provide a serious and dedicated environment for students to delve into their yogic journey, fostering self-discovery, holistic well-being, and personal transformation through consistent practice and perhaps a more rigorous curriculum. For exact offerings, it would be best to contact any center using this name directly in Haldwani.
