Gigi Hadid's toned glutes have been on display pretty much her entire modeling career. From strutting down the runway in the Victoria's Secret Fashion Show to stripping down to her skivvies in an ad campaign for Tommy Hilfiger, Hadid has provided plenty of moments for us to envy her fit backside.
As a result, we caught up with Gotham Gym and G-Box founder Rob Piela, who has personally trained Hadid, at his New York City gym. Piela took us through a butt-burning exercise that Hadid herself practices on the regular--and no it wasn't a squat in any way, shape, or form. Rather, it's a down-on-all-fours movement that works the major muscles in the booty.
I got down on my hands and knees to perform the leg-lifting exercises and I could feel a burn in my glutes, abs, and legs after just a few reps. Piela recommends starting out with 20 repetitions and moving up to 25 if you feel increasingly confident. He also said that you can add up to three pounds of ankle weights, but since your leg acts as a resistor on its own you can skip the weights if you'd rather keep things simple.
Watch the video above for the full tutorial, and get ready to start rocking those short shorts with your newly toned glutes!
