If someone on your holiday gift list has found a second home in the gym, then it's safe to say you have a fitness fanatic on your giving hands. A buff bod can never get enough fitness gear, so why not enable her healthy habit with these gift ideas? I have included a couple of items to add pep to at-home strength-training and a wicking tank top for serious sweat sessions. A great gym bag and a magnetic iPod case will help the gym rat in your life schlep to the gym in both style and comfort. If you choose to make a serious investment in your fit pal's workout life, I have included my favorite fitness heart rate monitor.
