The squat is one of the best ways to work and lift your butt. If you want an even more effective move, add some jumps to the mix. Fergie's trainer, Shaun Dreisbach, says the singer has a "love-hate relationship" with the jump squat. “Hates to do it, loves the results,” he tells Glamour.
Adding a jump to your squat lifts your butt muscles even more, while also adding a cardio component to the mix. For an even better lift, try to drop your squat lower on your last rep and hold for 10 to 30 seconds.
