If you ask us, any workout move you can do while lying on your back is ideal. Seriously, who doesn't rejoice the second any fitness instructor says, “Now lie back."

But that isn’t to say these moves won't have you feeling the burn. The glute bridge is perfect for building belfie-worthy buns.

To spice up this go-to, we had our very own Women’s Health fitness director, Jen Ator, come up with 15 bootylicious variations that’ll light a fire under your you know what. What’s more, these moves will deliver benefits far beyond your bottom.

“Your glutes are the biggest and most critical muscles in your entire body,” says Ator. “They assist in every major type of motion, from running to jumping to lifting. But, with all of the time we spend sitting behind desks, in cars, and on the couch, our butts can get a little lazy—literally, your glutes can forget how to fully engage. Lazy, weak glutes can lead to muscular imbalances and injury, low back pain, even poor posture.”

Glute bridges are one of the most beneficial and undervalued exercises out there, says Ator. Not only will this activate your glutes, it will strengthen your butt and hamstrings, as well.

Make one of these variations a staple in your routine by completing three sets of 10 to 20 reps. You can also use these moves as a warmup to wake up your booty before any workout. Shoot for two to three sets of 10 reps.

You’ll be bouncing dimes off that donk in no time.
