Sponsorship needed for the Fighters and the Gym

As with anything in life money is a necessity and The Viper Pit is no different, I would like to make the Gym better for everyone concerned, we need better equipment and it has to be able to make a difference to people's fitness, but good fitness equipment is very expensive so every penny we get will make a difference.

Question is: what piece of fitness equipment have you found to make a substantial difference to you ?
