The answer to this question will depend on many factors, such as the sport you are playing, your goals and more. The following article will explore these pros and cons in depth so that you can make an informed decision about which type of grip you should be using.
The advantage of hooks is that you won’t have to worry about the bar rolling or dropping out of your hands during a heavy deadlift or squat. Hook grip also takes up less time and energy than double overhand to single overhand transitions. The disadvantage is that it can be very uncomfortable and painful for some lifters, especially beginners. By using a double overhand grip on the bar and immediately transitioning to hook grip, you can get used to both grips without having to deal with this unpleasantness.
The disadvantages of straps is that they take up more time and energy than a simple transition from double overhand to single overhand. Straps also work against your calluses because they have a tendency to tear them off, which can be very painful. The advantage is that your hands will not get fatigued from holding the bar so tightly, allowing you to push more weight with each set and workout.
The main difference between straps and hook grip is that straps only provide a temporary anchor point for your fingers; they do not force the same degree of tightness that a hook grip does. This is why as mentioned above, straps are generally used to take the strain off your hands and allow you to push more weight; however, the drawback to this is that they have a tendency to tear your calluses off.
