To balance the two parallel careers, he drew inspiration from fields like discrete mathematics, combinatorics, graph theory, software testing, neuroscience, and learning theory to optimize his vocal practice. He has condensed his 10-hour workout into a powerful 1-hour workout (NaadYoga), and even a super effective 15-minute version for everyone.
