So you bought a healthy gift for your boyfriend, your sister, your mom ... why stop now? Resist the temptation to buy Grandma yet another holiday sweater and give her something that will contribute to her overall fitness instead.

Why? Because when it comes to fitness, age is just a number. Just like you need to get out and move at least five days a week, so do your parents and grandparents. Staying healthy and fit is a lifelong goal, and balance and flexibility become especially important as a person ages.

So when you go shopping for Gram and Pop-Pop, keep your eye out for one of these fit gifts.
