Inspiration hit in a chilly Dublin bathroom in 2005. Miami native Kino MacGregor decided to break from globetrotting as a guest teacher and return home to launch a studio. The following year, she opened Miami Life Center on a peaceful portion of Sixth Street. But the homey studio in the golden brick building is far from a dank Ireland restroom. The smell of incense and the sound of a trickling fountain fill the warm space where yogis can buy DVDs, props, and pleasantries. A single class costs $18, but the more you buy, the less you pay. Budget-conscious options are the $5 community class each week and a free monthly event covering topics from shamanic healing to life coaching. MacGregor, who is 30 years old, is an emerging standout among the deep-breathing set. The doctoral candidate in holistic health was recently named Yoga Journal's top 21 teachers under 40. She just released her first DVD and is the youngest of only 12 women in the world certified to teach high-energy Ashtanga yoga. And like her, much of the staff holds graduate degrees or has studied with the 93-year-old founder of Ashtanga yoga, Sri K. Pattabhi Jois, in India ... not Ireland.
