When practicing CrossFit or weightlifting, most of the time the weight that rises falls on our poor knees. There are moments of maximum effort in which when we do not have adequate protection it is very likely that in the long run, we are prone to suffer some injury while executing our routines. Of course, a refined technique and good footwear for CrossFit help us greatly to protect our joints. But nothing can beat having a pair of the best hinged braces for stability in some scenarios!
To avoid problems and accidents, many athletes choose to use knee pads when practicing this discipline.
