(WBBM NEWSRADIO) — Jennifer Conroyd came up with the idea for her pool-based workouts when she suffered a calf injury while preparing to run in the Chicago Marathon.
"My doctor said you can't run. I said you don't understand — I have to run this marathon,” she told WBBM Newsradio.
She said she Googled ways to stay in running shape without actually running on ground: “I came across this thing called aqua jogging or deep water running.”
That’s how LaGrange-based Fluid Running was started.

Not only did Conroyd run the marathon, she discovered how pool-based exercises are great for almost anyone. Being in the water allows people to work out regardless of their age, physical fitness or even chronic pain.
"Not just get an OK workout, but really a very high-quality cardio workout, completely full-body workout," she said.
What started as group classes in the western suburbs has now spread around the world, thanks to the launching of the Fluid Running app.
“Now, we're in every state in the country, multiple countries. We launched in Australia, the U.K., the E.U., Canada," Conroyd said.
