Most people wonder what the UFC super stars use to get into shape and to keep up their speed, well I will tell you. We received a call this morning that BJ Penn was using a resistance training suit called Mass. The Mass Suit increases your speed, strength, stamina, agility, power and explosion. It is the same resistance suit that Anderson Silva was seen wearing. Mass is the hottest training tool for all athletes on the market. You can also cut calories and lose weight.
