Can't afford a pricey gym membership? Don't have time to work out? Get a yoga mat for under $20 from Smarter. It's the perfect fitness staple for all your strength training needs: crunches, sit-ups, planks, stretching, squats. Throw it in a corner when you don't need it, and roll it out when you're ready to exercise. Keep it in front of the TV, or move it to your bedroom when you want to do something else. Take it to your friend's house, or don't. Sit on it, stand on it, lean on it... it really is the most versatile workout accessory. And it barely costs anything.Image Source: flickr.com/photos/lululemonathletica/4425366915
