You'll sweat everywhere and on everything, including your partner. Sweat is a good thing because it shows that you're working hard and you can't understand these people that stop exercising as soon as they start sweating because it'll ruin their hair and makeup... If you're working with a stranger then just address the elephant in the room at the beginning, "Hi, I will sweat all over you. I hope you're okay with this." It'll be worse when you're doing an ab workout though. The person with the gloves will be doing the work by punching the pads that their partner is holding over them. And because you're standing and are bending over your partner so that they can hit the pads, you're going to be dripping a little bit... maybe a lot.
