Since you're specifically interested in 200 hour TTCs in Rishikesh, let me focus on those. In addition to the schools I've already mentioned, I'd also recommend the Krishnamacharya Yoga Mandiram, Shiva Yoga Peeth, and Shri Hari Yoga School. Each of these schools offers a unique approach to yoga, and they're all highly respected in the yoga community. The courses offered by these schools are slightly different, so it's important to research each one to find the one that's right for you.
