Stacy Keibler's ultra toned physique appears as though it's the result of lengthy workout sessions.
But the 32-year-old model and actress has claimed it takes just 18 minutes, four or five times per week, to achieve a body hot enough to capture the attention of George Clooney, her boyfriend.
Juliet Kaska, a U.S. celebrity fitness trainer who works with the blonde beauty, told Self magazine that
'you'll burn extra calories for up to 48 hours after' performing the fast-paced routine.
