I am so excited that Spring is finally here! I've been riding my bike, going rock climbing, and hitting the pavement for outdoor runs. While I do all of this stuff because I love it, I know many of you are trying your hardest to get in shape for bikini season. Think you know which Spring activity will burn the most calories? Take my quiz to find out, and you'll be one step closer to a bikini-ready bod!
