Those Red Rocks stairs are going to look a lot less friendly while you run up them during this three-month butt kick. You’ll get a personal trainer who assigns daily individual workouts, nutrition tips from a HealthOne medical expert, and weekly mandatory workouts with a group of like-minded people on a quest to get healthy. Prizes like Southwest Airline vouchers, Red Rocks concert tickets, and golf lessons will be awarded to the most improved athlete, the top finisher in a final competition, and attendants with perfect attendance.  Tues 8 a.m.
