Hii Annie!
Frankly speaking, if you want to take up bodybuilding as a full time career, then definitely not in India. You can practice this sport along with a specific job of your choice. Because, in India and to that matter across world also, we are struggling to take this as a full time career option. Most of the famous bodybuilders do jobs simultaneously which are not related to bodybuilding, else it becomes hard to meet the two ends. You will definitely not own a Lamborghini with only bodybuilding. So, do practice your passion, it's very good, but also find stability in life via a job. Hope you understand.
Good Luck!
