As with PEDs, Conte went all in, rebuilding the BALCO model with a legal training method. He studied hypoxic-hyperoxic training and began accumulating and tinkering with equipment. His current gym includes a 12-foot high, 18-foot diameter, clear plastic tent connected to a series of small machines called oxygenators (they look like dehumidifiers and cost $5,000 each; Conte has 25 of them), which control the concentration of oxygen in the tent and allow boxers to simulate high-altitude training. Next to that is a smaller tent with a stationary bike used for active recovery. In other parts of the gym there are next-generation, treadmill-type machines connected to oxygenators and masks that the athletes wear in training to manipulate oxygen levels.
