As more yoga centers open up across the city, the convenience of having a yoga studio nearby is giving more people added incentive to give yoga a try. Reflecting this interest surge in yoga, teachers with certifications in a variety of yoga styles are showing up. Ashtanga, vinyasa, Bikram, jivamukthi, gentle flow, power yoga, hot fusion and sivananda are all styles that are available locally. With so many to choose from, a question often posed is : how do you know if you are already proficient in one style when you keep practicing so many? As if in answer to this question, Bikram Yoga Manila, the pioneer studio that introduced Bikram yoga to the Philippines, just conducted a series of posture seminars at its studios over the past 2 weeks. These seminars were aimed at giving Bikram yoga students specific knowledge about the set postures that comprise the Bikram yoga series.
