Fit Simplify offer five bands of varying resistance level for a very low price. The downside is that you will have to replace them after a couple of years since they tend to stretch.
Pro Resistance amounts are written on the bands
A lot of producers of resistance bands use color codes to distinguish between the levels of resistance of the different bands. Having it written on the band itself is much more straightforward. In total, there are three ways to distinguish the bands by resistance. The colors represent a certain resistance amount, the coded descriptions, like “x-light”, “medium” or “x-heavy” describe the same thing. Lastly, all of them has the resistance amount written on them.
