Yoga is the gateway drug of fitness for most of the ladies in my life. And because the practice isn't necessarily aimed at weight loss or counting calories, it's usually a safe bet for a gift. Instead of driving home the message with a fitness DVD, get them a cute yoga bag and mat. If this isn't enough to inspire your friend to check out a nearby class, they still have a functional tote that they can use for other things.
