Ashlee, Anna, and Rosario Make Toning Look Easy

Reebok had some star power on hand to debut its newest line of fitness footwear and apparel this week, including its latest EasyTone offerings. Young Hollywood starlets Ashlee Simpson-Wentz, Anna Kendrick, Rosario Dawson, Emmy Rossum, and Lindsay Price showed off the latest gear and worked out with celeb trainer Yumi Lee at a private residence in Los Angeles. At the event, Ashlee told E! that she used Reebok EasyTone shoes to lose the 50 pounds she gained while pregnant with baby Bronx.

"When I wanted to get back into shape, I worked out and these shoes are amazing because you can really feel them in your booty. But I also worked out and ate healthy."

While I am a little skeptical of the toning powers of EasyTone sneakers, I am loving that Anna used bottles of laundry detergent as hand weights — I'm trying this trick myself! It looks like celebs are loving the fitness events lately, because in the last few weeks we also saw Lo Bosworth, Kat Von D, Lindsay Lohan, and Audrina Patridge working out in support of Muscle Milk and Under Armour.
