The tranquil teachers at Jivamukti Yoga Charleston lead students in the pursuit of greater flexibility, fitness, and spiritual attunement. Jivamukti, one of the nine recognized styles of Hatha yoga, is based on five tenets, including bhakti, the cultivation of devotion and humility, and nada yoga, the practice of deep listening, chanting, and music. Reach multifaceted malleability in the 60-minute Spiritual Warrior class, a guided Vinyasa class that flows swiftly through warm-ups, poses, and meditation, or loosen up at Rockasana!, which uses the power of The Beatles, Led Zeppelin, and other members of the rock pantheon to vibrate out stress from the body and cause stiff joints to launch into freewheeling air-guitar solos. The schedule extends students seven days of sessions suited for every skill level.
