Kourtney Kardashian worked out in a sexy pair of sheer spandex on Monday, and when she left, she unzipped her hoodie and showed off her sexy abs!

Kourt zipped her top back up before dipping in to Il Pastaio in Beverly Hills for lunch, and after her meeting with Scott Disick over the weekend, it seems like she's hitting the gym to help alleviate some stress. Kourt and Scott brought the kids to lunch in Beverly Hills on Saturday, and none other than Kim K. was there to play mediator between the seemingly estranged couple.

"Everyone deals with hard times in their lives differently. I'm generally not a nervous person but I get anxious," Kardashian wrote on her website back in January. "One thing I've found that really helps is working out. I try to exercise 5 days a week. I usually start with a quick run or jumping rope to warm up. I have to do something fast to really kill it."

Scott, on the other hand, seems to seek relief in the party scene...
