As bare-leg and swim season approaches, the race to get fit is on.

Gyms across America are filling up. And this is the month that womens magazines offer scantily-clothed stars and gut-busting moves as inspiration to shave off the pounds by summer. Prime example: a bikini-clad Gwyneth Paltrow in this month's Self, offering diet and fitness advice. (Psst, see her trainer, Tracy Anderson's, instructional slideshow here.)

If all that isn't motivation enough, we were inspired by First Lady Michelle Obama and Second Lady Jill Biden, who appeared on The View the other day and talked about their Superwoman workout routines. Obama follows a twice-daily fitness regimen and Biden runs 5 miles every morning. Whew, we're tired just thinking about it.

If all this motivates you to get moving (it does us), you might want to check out our selection of this season's great activewear in the gallery below.
