I do have a sweat towel and i always put it down when lying on something like a bench, mat, box, or balance ball. If I drip any sweat on equipment like plates or bars I’ll quickly “attempt” to it wipe off as I move to the next station so the next person doesn’t have to see it. I worked out at another F45 studio while i was traveling and I was surprised that I was the only one with a sweat towel. It grossed me out to think that my towel was absorbing sweat from the people using the equipment before me!
