Home-Fitness is more and more becoming a thing now and with people realising how important it is to stay fit, they might think that they need a lot of expensive equipment to do so. But that's not true. The easiest way to step up your fitness game is by using rubber resistance bands. They can be used in a variety of different ways (with tons of tutorials on YouTube) and are available in different strengths. The thicker the rubber band, the stiffer it will be.
