Khloé Kardashian Got Sweaty for a Cause

Meet your latest spin classmate: Khloé Kardashian! The 32-year-old reality TV star hosted a charitable spin class at Cycle House in West Hollywood yesterday, and naturally, attendees were super excited to sweat it out with the reality star.

Proceeds from Saturday's spin class went to the Children's Hospital of Los Angeles' second annual Make March Matter fundraising campaign—a cause that Kim Kardashian has also been supporting this year. On her Instagram, Khloé explained that "Make March Matter is an annual fundraising campaign that brings local businesses and the community together to raise awareness of children's health." She went on to urge her fans to make a difference by using their voices for good: "Remember we all have a voice. And we can all use our voice and platform to do something positive."

For the charity ride, Kardashian wore a sporty all-black ensemble, including black leggings with white stripes, a cropped hoodie, huge silver hoops, and dark sunglasses. She brought along BFFs Malika and Khadijah Haqq for the ride, and the sisters were more than happy to sweat for the cause.
