Take 10 minutes from your day to strengthen and tone your backside with Cassey Ho, the founder of Blogilates [1]. This short but effective workout will leave your butt burning as you build muscle to tone and shape your booty. You don't need any equipment for this workout either — a few moves might challenge your balance, though. If that's the case just grab onto a chair to keep stable so you can focus on exercise. Ready? Press play, and get ready to feel the burn.
