Rebecca Romjin had difficult time losing baby weight

Rebecca Romjin may have been a slim super model back in the day, but that doesn’t mean it’s easier for her to drop some pounds.

In fact, Huffington Post reported the Ugly Betty actress calls weight loss “probably the hardest thing I've ever done in my life” in the March issue of Fitness magazine.

The 39-year-old, who gave birth to twins Dolly and Charlie back in December 2008, added that her pre-pregnancy fitness routines weren’t helping her get back into shape.

"Everything I did before I got pregnant -- like Pilates, which I had done for about 14 years -- didn't work anymore. I had to change the way I worked out, the way I ate-- everything."

According to Us Weekly, Romjin’s friend recommended she try Bikram yoga and that’s when things started changing.

"At first the idea of doing a 90-minute workout in a 105-degree room sounded like torture," she said. "But the sweating is exactly what I became addicted to. My body changed dramatically almost immediately. I'm stronger, I have more energy and I feel better, too. I was proud to get back into a bikini!"

Romjin lost a whopping 60 pounds through the routine. She also told the magazine that dieting wasn’t that easy as well.

"I went on a major diet about eight months ago. I cut out starch, dairy, fat, red meat, alcohol and sugar," the 5’ 11” star said. "Just being on a diet was weird for me. I had never been on one in my life, and suddenly I was counting calories and measuring my food. Cutting out sugar was definitely the hardest. The first week I thought I was going to die. The cravings were bad. But after that, it was easy."

She also credits hubby Jerry O'Connell for helping her.

"We love to take long bike rides. We have a tandem bike, and we go up in the hills near our home," she said of the 37-year-old.

Romjin also said, "Jerry is very show-offy when he's good at something, and he's pretty much good at everything. But he's been doing Bikram yoga for about a year now, and he isn't very flexible. I'm happy there's one thing I’m better at than he is."

We’re happy you’re happy too Rebecca!
