Colin Kaepernick is still training EVERY DAY -- busting his ass as if he'll be on an NFL roster in 2020, sources tell TMZ Sports.
We're told 32-year-old Colin has not broken his routine -- he's still hitting the gym and the field daily -- and as one source close to Colin put it, "He's in the best shape of his life."
Of course, Colin held a workout in 2019 to show NFL teams he still has a canon for an arm and the mobility that made him famous ... but he wasn't signed.
Many, including Kap, believe he was blackballed from the league for his kneeling demonstration (he hasn't been on a roster since the 2016 season) .
