SHAKE IT UP!
Toned backsides have been the new black ever since Beyoncé booty-bounced her way into our lives way back, and when Kim Kardashian broke the Internet. Squats may help us achieve a butt that Sir Mix-a-Lot would be proud of, but they can be repetitive. Rollerblading is an ultra-fun, no-gym-required alternative that targets, tones and tightens your butt, as well as your back and inner-thighs. If that wasn’t enough, blading is seriously fun.
