Better Grip
Gloves can help you get a better handle on the bars than your bare hands. And this is even more important if you are working out in hot weather. Some guys training in a garage or shop where the temperature can be enough to induce serious sweating. Gloves keep the bar from slipping out of your hand in these conditions. And that is vital for the final few reps where you don’t want to dare drop the bar.
Stronger Grip
Gloves not only give you a better grip on the bar, they build up your own grip at the same time. Gloves force your hands and forearms to have to work harder during the reps, and in turn give you a powerful grip. The thicker the gloves, the more the hands and forearms have to work. If you need to build up your forearms, gloves can help.
Smooth Grip
If you want a smoother pair of hands, gloves help here also. This is an individual preference and some guys like to build callouses on their hands. But if you don’t want callouses, gloves will help keep your hands smoother. Your lady may have a preference here, eh?
There are a variety of options when using weightlifting gloves. Most don't cost a lot and you can get a pair that covers more or less of your hand, depending upon your own preference. Some even come with a combined glove/wrist support mix, with a wrist wrap somewhat similar to what powerlifters use.
