You've heard of "Hot Yoga" and "Power Yoga". Jesus taught "Easy Yoga"

"Come to me, all you who labor and are burdened, and I will give you rest. Take my yoga upon you and learn from me, for I am meek and humble of heart; and you will find rest for yourselves. For my yoga is easy, and my burden light.” -- Matthew 11:28-30

Etymology note: The Sanskrit "yoga", the English "yoke", and the Greek "zugos" all come from the same Proto-Indo-European root, *yeug, meaning "to join".
