Bishnu Charan Ghosh was a prominent Indian physical culturist, yoga guru, and bodybuilder who significantly contributed to the popularization of yoga and physical fitness, particularly in the 20th century. Born in Calcutta, India, Ghosh was the younger brother of Paramahansa Yogananda, the renowned spiritual leader and author of "Autobiography of a Yogi."

Ghosh developed a unique system of yoga that combined traditional asanas with weight training and other physical exercises. His approach aimed to enhance physical strength, flexibility, and overall wellbeing. He believed that yoga was not just a spiritual practice but also a powerful tool for physical development and healing. He meticulously studied the effects of yoga postures on the human body, documenting his findings and incorporating them into his teaching methods.

Ghosh's influence extended beyond India as he traveled internationally, demonstrating his yoga techniques and promoting the benefits of physical culture. He authored several books on yoga and physical fitness, sharing his knowledge and insights with a wider audience. Many notable figures, including bodybuilders and athletes, sought his guidance, recognizing the value of his integrated approach to physical development. Bishnu Charan Ghosh's legacy lies in his pioneering work in blending yoga with physical culture, making yoga accessible to a broader audience, and emphasizing its potential for both physical and mental wellbeing.
