Chad Johnson tried to top Cardinals rookie by running on inclined treadmill at 24 mph

Last week we showed you Robert Gil, the 29-year-old Arizona Cardinals rookie, who ran on a treadmill at 25 MPH. In an attempt to one-up the rookie, Chad Johnson posted this video on Twitter of him running on a treadmill at a 2.5% incline at 24 MPH. Seems the 35-year-old NFL free-agent still has the athleticism.
