Based on what we've seen, we believe it!
The only way to survive a tour and a residency in Vegas is to be in the best shape of your life, and according to trainer Tony Martinez, Britney Spears has been punishing her body with incredible fitness (in a good way)!
"I like to incorporate sports like baseball or basketball into my workouts. The idea is work out smarter not harder."
They would workout 3-4 times a week for four months! He continued:
"I like to have fun and light humor and have you laughing the whole time. We will get your work done but I want you to have fun."
We think that's something that's missing from a lot of personal trainer's methods — sometimes, being cold and borderline mean doesn't get the motivation done!
He went on:
"She is a tremendous athlete. She likes to be very strong and aggressive in her workouts. I kept telling her to stop making it look too easy. It was like a competition with us! She always had a positive attitude. She did lose weight and she has a lot more muscle. She lost a lot of body fat."
Diet-wise, he had her eat five times a day, including a special chicken salad with balsamic dressing that she couldn't get enough of!
So fab! We can't wait to see that body in action!
It can't come soon enough!
