Bio Ritmo Fitness Centre distributed T-shirts with a special feature to its students, as well as to people visiting the city’s public parks where it is established. When it is dry, it is only an ordinary T-shirt, which reads: You look better when you sweat. By getting sweaty due to the person's perspiration , the T-shirt reveals a tattoo drawing, which enhances both the male and female shape.

During those weeks when the gift was distributed, there was a large increase in the amount of postings and comments from Bio Ritmo profiles on the social networks, in addition to a 6% increase in the amount of registrations for monthly plans.
