Kate Middleton’s exercise for her flat stomach has been revealed, how does Meghan achieve her lithe look.
Meghan’s personal trainer of three years, Craig McNamee founder of Catalyst Health in Toronto, Canada, told WomensHealthMag.com the Duchess of Sussex always took her exercise very seriously.
He said: “Meghan Markle’s fitness definitely takes priority; she’s very focused on her health.
“When she gets to the gym, there’s no real complaining. She gets down to business right away and really enjoys it.”
Craig revealed that his workouts with Meghan include a five minute cardio warm-up, followed by stretching, a 30 minute circuit with light weights and stretching to cool down.
Additionally, Craig revealed Meghan’s favourite move to work her glute muscles, the surpine glute bridge.
He claimed it is a crucial part of Meghan’s routine, adding: “This one will set your glutes on fire.”
The move sees someone resting their shoulders on a bench, facing upwards with her knees bent in a bridge position.
Holding a weight across their hips they lower their buttocks to the floor and then thrust them back up to the original position.

Belly fat isn’t just an issue because of how it looks, it could actually be a sign of a more serious health problem, which is why it’s very important that slimmers stay on top of it.
