But the reality TV star and mum-of-three is no slacker, she has revealed on her blog exactly how she sticks to her exercise routine while on the road.
"Exercising is a part of my daily routine. So, even though I like to relax on vacation, getting a workout in is still important to me," the 38-year-old writes. "Also, working out while traveling really helps me with jet lag and makes starting to work out again when I'm back at home not as difficult."
These are the five simple moves she swears by.
"A powerwalk on the beach is always a great workout, since sand makes your leg muscles work harder. To kick this up a notch, mix in some lunges at the beginning and end of your walk. Since walking—or lunging—on sand provides instability, you'll work that much harder to keep your balance."
"While in Egypt, I did 200 chair squats to help keep my hamstrings, glutes, and quads toned. Just pretend you are about to sit on a chair and pop up into standing position while engaging your core."
"Find a fixed (and strong!) edge—like a tall bathtub or steps—and lower your body up and down with your legs straight out. Keep the move slow and controlled."
"Classic, old-school push-ups may be the least fun exercise, but they are so effective in toning your upper body and adding definition to your arms. If push-ups are too hard at first, modify the move and anchor with your knees, instead of with your toes."
We're definitely adding these to our next holiday itinerary.
