Like most locations in the national chain, 24 Hour Fitness in Highland is packed every day of the week with eager nine-to-fivers, gym rats and hardbodies elbowing for treadmills. What's unique to this spot is its penchant for combining cardio-machine workouts and foodie television. No matter the time of day, at least two of the many TVs entertaining fitness freaks are locked on the Food Network. Members at this gym are as intent on sweating it out as they are on watching Guy Fieri chowing on roadside barbecue or Giada whipping up homemade Italian specialties. They're adding calories just by watching, but at least they're working them off.
