When one is looking for the best tush-toning exercises, who better to ask than the woman who consistently whips Selena Gomez's booty into shape?

In fact, she demonstrated it so beautifully in her 45-minute Class Fitsugar video workout. Check it out:
"Bridging with a TheraBand is incredible," Amy told POPSUGAR. "Even just bridging in general — there are so many variations you can do: pulsing up, single-leg bridges, moving side to side . . . and if you're doing it right, you're also activating your arms and stomach!"
