There's nothing like seeing pictures of beautiful celebrities working out to get your butt motivated for the gym. Nicollette Sheridan gets her exercise jogging on the beach while vacationing in St. Barts.

Felicity Huffman and husband  William H. Macy ran the ‘Nautica Malibu Triathlon‘ which was held at Zuma Beach in California.

Supermodel Elle MacPherson had a very physical Christmas this year. She spent the holiday surfing on an Australian beach. With nickname "The Body" Elle's sure to keep her body in perfect shape.

Dancing With The Stars runner up Mario Lopez Jogs on the Beach to keep his body looking right.

Saying Hillary Swank has an amazing body is an understatement. This woman really does have the best body. She's thin but not too think and toned but not too muscular.

Here's Jessica leaving the gym after yet another workout!

She's been wearing lots of baggy clothing lately. I'm wondering when she'll reveal her new body...

There is no way that Christina Milian could have that body with out putting some serious time in at the gym. You can tell she's worked very hard for her figure.

Jessica shows off her yoga body while lounging in the sun.

In case you're in need of some motivation to get your butt to the gym here's thisweek's most enviable celebritity bikini bodies:

"I would definitely be more inclined to go to a dinner party than slave away in the gym. Food and people are life's greatest pleasures!" Sarah Jessica Parker

I saw this the other day and just had to post it. Sorry if it's a little corny.
