Theraband is a brand of resistance bands that are currently available for the general public to use for Resistance training. The nice thing about these bands, as opposed to others I have tried, is that these come in simple, unique colors to differentiate the levels of difficulty. Other bands I have used were off shades of the same color, making remembering the system difficult. Also these bands are strong, and hardly snap or tear with use. They are used a lot in rehab/therapy settings, so there are a large number of exercises available to try them out with. The only real downside to this product is the cost, they are not cheap to buy, and if you are lucky you can just get some from your therapist or rehab setting-that makes it much more cost effective.
