A nationwide fitness chain has banned cable news from the TV sets in its gyms, saying that today's toxic political climate is incompatible with its "healthy way of life philosophy." Life Time Fitness, which operates 128 gyms, says the move comes in response to numerous customer requests. Gym-goer Peter Glessing of St. Louis Park, Minn., says he will miss the stimulating indignation provided by cable news, which gave him "an extra motivation for exercising."
