Madonna's Pre-Grammys Workout: Spinning with Lourdes

Yep, that was Madonna, who got her Grammy weekend cardio in at Cycle House in West Hollywood.
The famously fit singer and her daughter Lourdes Leon, 17, showed up together for a spin class on Friday. The pop icon, 55, loved the workout so much that she returned Saturday for a second class.
Arriving in black top, black beanie and sunglasses – and also what one source said was a grill – Madonna donned black riding gloves for the 45-minute full-body ride. For the arms section of the class, the buff mom of four chose 2 lb. weights to complete her workout.
She later cooled down with her trainer Nicole Winhoffer inside the spinning studio as the rest of her class stretched outside in a courtyard.
Madonna is set to perform on the Grammy Awards show Sunday night, making her first appearance since 2006 when the seven-time Grammy winner shared the stage with Gorillaz.
