Madonna is famous for her dedication to diet and exercise, so it's no surprise the ripped pop icon enjoyed a 45-minute spinning class shortly before performing at the 2014 Grammy Awards.
Madonna and her 15-year-old daughter Lourdes completed a rigorous indoor spin class at Cycle House in Los Angeles before walking the Grammy red carpet. Sources told E! Madonna used two-pound arm weights during the arm-toning portion of the rigorous cardio class.
Ironically, Madonna's former longtime trainer, Tracy Anderson, slammed spinning workouts for causing thick thighs.
"Spin may burn calories in the short term, but it'll bulk up your thighs," Tracy. "I have women who come into my office after spinning exclusively for six months, wondering why they can't fit into their jeans."
Weight-loss experts immediately ripped into Anderson for her comments, saying spinning classes do not cause weight gain or fat thighs.
Meanwhile, the super-fit Madonna insists she has no intention of slowing down at age 55. "I'm not going to slow down, get off this ride, stay home and get fat!" said the Material Girl.
The mom of four said there's no secret to being fit and youthful. "It's all about hard work," said Madonna, who lifts weights and does cardio, yoga and Pilates workouts.
"There is no easy way. If you want to know how I look like I do, it's diet and exercise and constantly being careful."
Madonna reportedly follows the macrobiotic diet, which eliminates meat, wheat, eggs, and dairy and emphasizes nuts, grains, and vegetables. She typically works out up to two hours every day.
Madonna recently came under fire from fans for her swollen, heavily-Botoxed face. The pop star has never admitted getting plastic surgery, but said she's open to the idea. "I don’t like the idea of someone putting you to sleep, then taking knives to you," she said.
"Everybody knows my exercise regimen," said Madonna. "And I avail myself of everything rejuvenating and moisturizing and good for the skin. I am not going to hold a press conference if I have plastic surgery. But as I have said many times, I think about it like everybody. And I sure don’t rule it out."
