A fired-up Donald Trump is back with a fourth group of 18 entrepreneurial wannabes. Their first task: work up and promote a new fitness class for Bally's Gym. But first, they convene at Trump's golf club in Bedminster, N.J., where the Donald divides them into teams---by gender (the men form Excel Corp., while the women call themselves Capital Edge). Then it's a race---literally---back to Manhattan. The winner gets to choose between two prospective Bally locations.
