Playback singer Sonu Niigaam is looking fit as ever at 36, all thanks to Baba Ramdev's exercises that he practices religiously everyday.

The singer, who has sung popular numbers like "Ye Dil Deewana" and "Panchhi Nadiyaan", is sporting a new, refreshed look for his role as a judge on Star Plus' reality show "Chhote Ustaad".

The show is going on air Saturday, and Sonu sports a new hairdo, a revamped wardrobe and a well-toned body on the show. His yoga sessions also help him in building stamina and focus, says a source close to the singer.

Sonu will judge the show along with Pakistani sufi singer Rahat Fateh Ali Khan.
