A recent survey of 10,000 women in the UK has uncovered the secret to being a gym rat: It's predestined by your zodiac sign. Outlandish? Sure. But we're totally intrigued by which signs are most likely to exercise and which ones are more likely to be slackers.

The celeb-focused UK site Hello! Daily News has done some serious scientific research to back up these claims: They listed all of the fittest celebs for each zodiac sign, and apparently, the "depth of celebrities born under Leo" supports the claim that Leos are most likely to be cardio-crazy.

The survey's results seem more lucky coincidence than science, but it's still fun to see where your sign ranks. Here, from most to least fit, are the survey results..
