BRB - gone skippin'.

Granted that Gigi Hadid has supermodel genes running in her veins, but we're always keen to hear her fitness-related tidbits.

The definitive model of the social media age has always advocated for a lifestyle that's both balanced and healthy: and for that we salute her. She's notably fond of her beloved cheeseburgers, but equally as passionate about exercising for its physical and mental benefits.

The 23-year-old is a regular sighting at New York's old-school-style Gotham Gym - in fact, the boxing gym has become a veritable model hot spot in recent years.

Gotham Gym owner Rob Piela has previously said that Hadid is not afraid of getting down and dirty in the ring (and judging by the moment when she fought back against a prankster who invaded her personal space, yeah..we believe him!)

“Staying fit is all about consistency. Don’t miss workout days; don’t get lazy in the winter," Piela said. “It’s all about how hard you work and how much you put in—Gigi is a hard worker.”

So, what do these training sessions look like?

Piela said that when working with Hadid they will switch between cardio bursts of boxing and some 'hardcore' floor work to chisel her abs.

To keep former volleyball player Hadid in catwalk-ready shape, Piela swears by donkey kicks. 

"Start on all fours, knees in line with hips, hands beneath your shoulders. Maintaining a level posture, and a 90-degree bend in your leg, raise your right foot (foot flexed) towards the ceiling. Return to your starting position. Repeat on the other side. Increase the difficulty with ankle weights," he told Women's Health UK.

However, here's the ~ real crunch ~ of Hadid's fitness routine. Obviously we can't get access to Piela, who also counts actors like Hugh (ripped) Jackman and pro athletes among his clients. The fitness expert once told W Magazine that the best way to "slim and tone legs" is with this under-valued piece of equipment.

“We start with jump rope—there’s no better way to slim down legs—and we end with ballet-inspired floor exercises,” he said.

“In the middle, we box,” he added, explaining that it is a perfect balance of cardio and resistance training. “All the girls I work with can fight—boxing is great for someone who’s competitive.” 

As most jump ropes cost less than five quid and you can skip from your own home or local park, it's a great and economical way to work up a sweat.
