Weight lifting hooks help take the weight of your wrists.
Lifting hooks with straps give you better grip.
A better grip means more intensity while you exercise. There is no point in decreasing the intensity because of a weak grip.
They are very light in weight and easy for you to carry around.
A premium quality weight lifting hook grip will not break and will be of use for quite a long time.
Since your hands and wrists do not get as much rest in the gym as some other parts of the body, it becomes even more important to take as much strain off them as possible. A weight lifting hook does that.
