Because they're not the only way to get a better butt.
While it's true that squats can work your glutes from every angle, they get pretty boring after, oh, a second. It's why you really can't sustain a tight tush on squats alone. Besides, there are plenty of variations which, when performed together, could put the basic squat out of business. (You're welcome.)
Ready to, ahem, round out your glute routine? Try these butt moves designed by Chelsea Dornan, a NYC-based personal trainer, and modeled by Brittany Perille Yobe, a certified personal trainer who's racked up an Instagram following of more than 783,000 people thanks to her butt-centric feed.
