I have designed some buttons implanted in the supports of the bars, dumbbells... That when pressed by the weight, they take some money from the customers' fees to give them to Malaria research, since it is one of the diseases that is wanted to eradicate in SDG 3. It will be used by all those who want to train in the Gym.

The operation is simple, the person performs the exercise and when he leaves the dumbbells, bars... Again, the buttons will be pressed, and the GYM takes some money from the clients' fees for Malaria research.
