Grips aren’t a necessity but can be used as a tool. You might see CrossFitters wearing gymnastics grips for bar work. Since this is where most rips occur, grips can be used to help maintain a grip on the bar during larger sets. However, they are still acting as a barrier against your skin, so can still cause hand tears. Some of the most popular grips used by CrossFit athletes are Bear Komplex, and Alec Smith grips. They have been specifically designed for CrossFit performance and tough workouts.
