"The problem is, when you come back in you're sweating, so I wait until the very last minute before putting on my shirt so that it's not covered in sweat"

Paul Ince is referring to the difficulty of getting dressed after a workout. He is stating that when he comes back from an exercise, he is typically sweating, so he waits up until the really eleventh hour before putting on his shirt so that it is not covered in sweat. This is a common problem for individuals who work out, as it can be tough to get dressed when you are still sweaty. It is also a problem since sweat can trigger clothing to end up being stained or foul-smelling. Paul Ince's service is to wait till the extremely eleventh hour prior to placing on his shirt, so that it is not covered in sweat. This is an useful option that many people can use to avoid needing to deal with sweat-stained clothing.
