Madonna's going to live forever

Sources believe she exercises around three hours a day.

She starts with yoga at a home gym. She moves on to a North London Pilates studio (where she is occasionally joined by Gwyneth Paltrow and Stella McCartney). For a third session after lunch, she chooses from a variety of options including karate, swimming, weightlifting, running, cycling, and occasionally horse riding.

The Daily Mail claims she also uses a StairMaster in her office as she takes calls. She supposedly maintained a 45-minute-a-day StairMaster regime until the day before giving birth to her first child, Lourdes.

Madonna’s workout tastes can also run to the more exotic. She reportedly uses a complex device called a Gyrotonic Expansion System that is said to stretch and tone smaller muscles. In the wake of her equestrian accident, she also reportedly bought a Power Plate, a vibrating platform alleged to help bone density and fight osteoporosis, according to the Power Plate web site.
