Britney Spears has credited regular yoga sessions with helping her deal with anxiety issues.

The Toxic hitmaker has adopted a new workout regime to get fit before taking up a rumoured residency in Las Vegas, and the singer has revealed she finds her yoga classes extremely therapeutic.

She tells U.S. radio host Ryan Seacrest, "I love my yoga! I'm doing a lot of yoga right now. It's like my go-to between all (my) anxiety and everything."

However, Spears admits she wasn't always fond of the stress-busting exercise routines: "The first time I did yoga I didn't like it at all. I think the key is finding a good teacher, someone you kind of connect with and if you do find that person then it doesn't feel like you're bored or impatient because I've been in tons of classes where I'm so over it and I can't deal (sic) and want it to end, but I think if you find the right instructor, it does wonders for your body."
