If you stay ready, you don't have to GET ready ... and Colin Kaepernick looks ready!
The quarterback hit up a gym in New York City on Sunday to get his pump on ... just in case that phone rings from an NFL team.
Kaep was sporting Nike head to toe -- the company has not only stuck by Colin, but has featured him in ad campaigns over the years.
Our Kaep sources tell us Colin's been hitting the gym DAILY and working out with a QB coach regularly ever since he last stepped foot on an NFL field back in 2016.
