Spring is almost here, at least according to the calendar. To psych yourself up for the changing of the seasons, we asked you to share your fitness must haves for this week's challenge of the Get Fit For 2011 giveaway. We're joining in the fun, too! Here are five pieces of fitness gear that are helping us gear up for Spring. Be sure to share your fitness must haves in our Get Fit For 2011 group to enter our weekly giveaway.
