If you want to make the most out of your workout, you’d probably reach for water or a protein drink after you leave the gym.

Now Coca-Cola wants you to reach for a tall glass of Coke. But is that really a good idea?

Absolutely not, Tom Stout of Burston Marketing said on Michiana’s Morning News with Mark McGill on Friday morning.

“It’s obviously a marketing deal because their sales are in the tank,” he said. “They’re looking for new markets.” The health and fitness market seems to be the one they’ve chosen.

Coca-Cola isn’t the only soda company seeing declines in sales. The year of 2014 marked the 10th year in a row that Pepsi and Coca-Cola saw declining sales, Fortune reported. Consumers instead are buying more bottled water, juices, teas and other drinks that are typically seen as healthier.
