The purpose of a wrist wrap is to provide support to the wrist joint during heavy or max effort lifts in pressing movements and overhead lifts. During these movements, the wrist can be pulled into excessive extension under load and result in compromised mechanics, possible injury, and failed lifts.The wrist wraps/straps help us while lifting weight. If your intent is to improve the size and strength of a certain muscle group, and using straps improves your ability to do so, wear them without shame!
