Kylie Jenner recently revealed her $29 waist-trimming secret

Kylie worked out wearing a Sweet Sweat waist trimmer, which has 150,000 five-star reviews on Amazon

Kylie Jenner has been a fan of the Sweet Sweat waist trimmer for years, and she just proved she’s still a fan by wearing it during her last workout.

The new mom, who has previously stated that waist trimmers help her with her workouts and posture, published an Instagram story in which she can be seen working up a sweat on a treadmill while wearing the Sweet Sweat belt.

Amazon sells the Sweet Sweat trimmer, which retails for $29, starting from $20.95 / £29.49. It has an impressive 150,000 five-star ratings, earning it an overall 4.7 stars.

The waist trimmer from Sweet Sweat is made of flexible premium neoprene that repels moisture and has double support and a velcro clasp for a precise fit around your stomach.

“This thing is great!” enthused one shopper. “ I wear this belt while I run, go on walks, and when I’m doing squats, sit ups, planks etc. I’ve been using it for a month… With diet, exercise, and using the waist trainer, I have lost 2+inches off my waist in less than a month. I sweat more when I wear it, and my workouts feel more effective and efficient.”

If you want to try one for the first time, it’s also a more affordable option than, say, Kim Kardashian’s favourite $68 (£ 66) waist trainer from SKIMS.

According to Sports Research, the brand behind the waist trimmer, the workout aide will “help you get the most out of your next cardio, circuit or high-intensity interval training session”.

Kylie’s exercise post, which came after she attended her sister Kourtney Kardashian’s lavish Italian wedding to Travis Barker of Blink-182, was just the latest example of her enthusiasm for waist trimmers as a workout-enhancing method.

a mother of two Kylie said years ago that she began wearing them after watching how they helped her elder sisters tone their bodies.

In a 2015 Instagram post about a Waistworld trimmer, she revealed, “I love a little extra help… I’m officially obsessed with after seeing how bomb my sisters look. It also helps with my posture.”
