Recently single Kourtney Kardashian looked happy and svelte as she posed in an Instagram snap

She might have only been single since splitting with Scott Disick July, but Kourtney Kardashian certainly isn’t letting it get her down.

The mum-of-three was celebrating the US holiday Labor Day yesterday (September 7) and made sure all her Instagram followers knew about it. Kourtney posed on a yellow tricycle wearing a revealing gold bikini, and showed off her toned figure.

‘Happy Labor Day! wait, there’s no emoji for a tricycle with no handles?!’ she wrote under the picture. Riding around on a trike with no handles sounds like it could be quite dangerous – no wonder Kourtney stuck to posing!

Kourtney’s fab bod is the result of a rigorous workout with her trainer Don Brooks, who she exercises with three to five times a week. He recently told E! that she’d been following what he calls the Don-A-Matrix program, which is much less kinky than it sounds. It’s a workout inspired by a sports game of four quarters, with each quarter consisting of two different exercise moves.

Don also revealed that Kourtney uses resistant bands to shape up, and tones her abs with planks. He’s been training with her ever since she gave birth to her second child, Penelope, and says that he was recommended to her by the Black Eyed Peas’ Fergie.

One thing’s for sure – Don has certainly got Kourtney looking stunning!
