With stars hitting the beach like whoa over this long Fourth of July weekend, we're taking a look at some of the most enviable physiques so far this year.
And after taking a peek at some of the hottest stomachs out there, it's clear that "Dancing with the Stars" does a body good.
Both contestant Kellie Pickler and former dancing pro Maksim Chmerkovskiy have two of the most awesome abs around.
And representing for the Over 40 set, we've got Mariah Carey -- who managed to fit into one of the skimpiest monokinis ever in a very revealing pic for her Twitter followers.
But they're only the tip of the iceberg.
Check out the gallery above to find out who has been spending a lot of time in the gym ... and see who could benefit from a few more trips!
Plus, see shots of stars like Jessica Simpson and Kim Kardashian, who showed off their big bellies in bikinis before they popped!
