I love resistance bands because they're easy to take with me places if I feel like working out somewhere other than my living room and they are inexpensive and a great addition to any home gym. The good thing about resistance bands too, is they can accommodate a lot of exercises and strength training moves. You can work out any part of your body with resistance bands and they come in a variety of types, tightnesses (for more resistance, so they are customizable to your level of fitness) and colors (because, fun). I have some virtually fit in my pocket. I've created this resistance band ab workout to be simple to follow and depending on your fitness level, you can make it harder or easier.
