This product has made my gym career much easier! Before, when i used to lift dumbbells, i used to get a lot of bruises and my hands used to hurt because of them.
Now that i have these gloves, they make lifting weights less stressful on the hand. However, don't think you will get an advantage of using them, as you will still be lifting the weight that you are looking at above your head :D
I am no way a pro, but from my little experience, and my 2x a week at the gym, i can say that these gloves have helped me a lot, not only for weights, but rowing and other exercises that demand pulling or pushing with your hands.
On a final note, the mesh means that your hands breath when exercising, whereas other products don't let you do this!
Hope that helps a little!
