Heidi Montag's beauty standards have changed
The 37-year-old star admits that her idea of the perfect body has changed markedly over the years.
She told Us Weekly: "I used to want skinny legs and the gap in between the thighs - I thought that was such a staple of being fit. Now my opinion of what’s sexy and what’s healthy is so different."
Heidi has upped her fitness efforts in recent times, while she's also overhauled her diet, cutting down on things such as sugar, bread and alcohol.
The TV star has lost 22 pounds in just three months and she now feels better than she has in years.
Heidi - who has been married to Spencer Pratt since 2008 - shared: "I love how strong and toned my arms are. It’s been really fun to flex for my husband. I’m like, ‘Yeah, look at these!’ This is the best I’ve ever felt."
Heidi has actually been inspired by Jennifer Lopez, observing that it's possible to be "hot and fit and older and timeless".
Asked if she's the most confident she's ever been, Heidi replied: "Yes, especially considering my age.
"I can’t really compare myself to when I was 20, lifting weights and having a perfectly flat stomach. I’m not going to have the same body, and that’s OK.
"I look at someone like Jennifer Lopez, and that makes me think you can be hot and fit and older and timeless."
Heidi believes getting more sleep has been one of the keys to her recent transformation.
She shared: "I cut out a lot of carbs. I had bread once a day, and I cut down on sugar and alcohol. I also made sure to get a little bit more sleep, which is a big deal."
