Resistance bands are elastic exercise equipment that provide variable levels of resistance through their length. They come in different colors and levels of resistance, typically marked with numbers indicating how much force they can handle before stretching too far. Resistance bands are versatile tools for strength training, as they allow users to perform a wide range of exercises targeting various muscle groups. These include bicep curls, tricep extensions, shoulder presses, lunges and squats, among others. The resistance provided by the band changes depending on how it is wrapped around the user's limbs or body, allowing for a challenging workout that can be easily adjusted to suit individual needs and abilities.
