Dez Bryant isn't joking around with his offseason workout regimen.

The Cowboys' star receiver, who led the NFL with 16 touchdown receptions in 2014, recently posted some videos of his training routine.

It's safe to say his six pack isn't going anywhere.

Sports Illustrated recently ranked Bryant as the fifth fittest athlete in all of sports, and it's hard to argue after seeing these videos. Bryant, who is 6-foot-2 and 220 pounds, pulls his body up with relative ease.

The video inspired a wide range of reaction on Twitter:

Bryant had a career year in 2014. He caught 88 passes for 1,320 yards and earned his second Pro Bowl nod. He's a free agent this offseason and should be in line for a hefty contract.

Perhaps Bryant is more motivated these days after his team's season ended in dramatically heartbreaking fashion. The Cowboys lost to the Packers in the NFC divisional round, and that game will be largely remembered for the crucial fourth down pass that Bryant couldn't hold on to.

As some snarky fans pointed out, this workout won't help with similar situations in 2015:
