Resistance Bands are a wonderful addition to your home exercise equipment. They are very cheap these days and are easy to store taking up very little space. Some of the top brands have resistance bands that are very costly, im my opinion you are paying for the name. But you can find them in some stores for affordable prices. I would suggest buying the cheap ones to make sure this is the type of strength training that you are interested in. The first resistance band I purchased cost an amazing 2 dollars in a reduced area within a retail store. I got lucky, and that resistance band is still going strong today. I needed more resistance so I recently bought a resistance band that has 3 removable bands with varying degrees of resistance. You can start with one band and as you get stronger you can add one or more bands for a tougher workout. Most resistance bands come with different exercises that you can do working on different parts of the body. So if you don't want to spend a ton of money on a set of weights, resistance bands are the way to go, they are much cheaper and very easy to store, taking up little or no space.
