Exercise Bands are inexpensive, lightweight, highly portable, and low-powder for minimal mess. Used by physical therapists, occupational therapists, athletic trainers and sports medicine practitioners since 1975 for rehabilitation, conditioning and training. They can be used to condition any part of the body by simply cutting an appropriate length of band. The band can be used as a cut strip or it can be knotted to form a loop. Each exercise band is color-coded to show its resistance level using the TheraBand® trademarked color sequence. Any color exercise band can be used as part of a progressive resistance exercise program.
