There are many good reasons why Jessica Biel constantly takes our fittest female crown. There's her 2010 hike to the top of Mount Kilimanjaro, her fit-and-fun lifestyle (including biking around town with Justin Timberlake), and her enviably toned physique. In 2012, Jessica kicked butt yet again with Total Recall, which she prepared for with martial arts classes. This year, she kept up her routine, including circuit training and lots of yoga. With all that on her fitness plate, it's no wonder Mrs. Timberlake is always the fit celeb we can't get enough of!
These actresses never fail to make yoga class, strap on running shoes for a quick jog, or spend more time surfing and swimming than sunning on the beach
