Jennifer Lopez Works Out Hard to Work It Hard

If you worked out as much as Jennifer Lopez apparently does then maybe you'd also want to put on an skintight shimmery catsuit and have a guy lift you above his head on New Year's Eve — just because you can!

"It's true I could serve coffee using my rear as a ledge, but I'm proud of my butt," Jennifer told the New York Post.  "A dress shouldn't look like a coat hanger. Skinny girls miss out."

So how does she get the figure — and a butt — she's so proud of?

Boxing.

Jennifer said her personal trainers got her hooked to it as a way to get in shape for her 1998 role in Out of Sight.

She claims to have a "wild side" that the sport goes perfectly with and helps her with her cardiovascular work-out.

In addition to boxing, J.Lo runs, does weights, uses StairMaster and does "light circuit training and cardio" several times a week and "biking, weight machines and lunges to keep those thigh muscles firm."

Getting into her New Year's Eve outfit must have quite the work-out as well!
