Wikipedia gives the following as an overview of Yoga:
“The origins of Yoga may date back to pre-vedic Indian traditions. The earliest accounts of yoga-practices are to be found in the Buddhist Nikayas. Parallel developments were recorded around 400 CE in the Yoga Sutras of Patanjali, which combines pre–philosophical speculations and diverse ascetic practices of the first millennium BCE with Samkhya-philosophy. Hatha yoga emerged from tantra by the turn of the first millennium. Gurus from India later introduced yoga to the west, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. This form of yoga is often called Hatha yoga.”

In terms of medical viewpoints, they range from concerns about physical injuries [ usually resulting from newcomers trying to do more than their bodies are strong enough to do] to studies about the practice of yoga’s results on depression, blood pressure, cancer, and other medical problems.

From my research, a position that seems to encompass the safest and best results is a system called “Praise Moves” developed by Laurette Willis. She has built a system which uses the ‘safest’ yoga poses (minimizing the potential for injury) with Christian worship songs and Bible study. A joyous praise to God.
The following videos present several of the views on Yoga and how it can and/or cannot interface with Christianity:
