Apart from being a world-renowned supermodel, Gigi Hadid is also known for not being a quitter in the gym. Our girl even conducted an entire interview while holding a plank:
No wonder she has an envy-worthy midsection. ;)
But according to one of her personal trainers, Andrea Orbeck, Gigi has a couple more go-to core workouts that help sculpt her abs: Single-Leg Side Plank and Knees to Elbows Crunch.
Orbeck says these two workouts are effective because, "[incorporating the] movement of both the legs and arms are considered 'full recruitment' movements. The abdominal and back muscles are key components of this muscular network, and provide the strength to keep the body upright for movement."
And obviously, they work.
Here's how to execute them:
Single-Leg Side Plank: Get into the side plank position. Keep your back straight then slowly lift your leg toward the ceiling. Hold for 10 seconds.
Knees to Elbows Crunch: Lie on your back with feet on the floor and hands at your temples. Try to touch your elbows and knees together over your stomach. Extend your legs as far as you can. Do for one whole minute.
