If there is anyone who has authority on the proper way to sprint it is undoubtedly Usain Bolt.

As the fastest man in history, Usain Bolt definitely has the authority to critique sprinting techniques.

Yahoo! Sports recently caught up with Bolt for a quick session where he analyzed the runs of some other iconic athletes. The Jamaican sprinter, as well as world titleholders, watched three NFL players sprinting in the 40-yard dash at the NFL Combine and weighed in on the performances.

The first to be judged was 40-yard dash world record holder John Ross, who did not escape criticism. According to Bolt, Ross leaned forward a bit too much for his liking, and need to correct his form.

“For me, he didn’t get into his running,” Bolt told the interviewer. “30 metres it’s good but you gotta get up and run.” he added. The iconic sprinter would soon hit a lighter note, hilariously claiming he could run the same time while wearing joggers.

However, it was the sprinter’s critique of NFL legend Tom Brady which drew a few chuckles. While watching a clip of the New England Patriots star doing the 40-yard dash Bolt contain his laughter.

“Oh my gosh. Everything is bad there, everything is bad there,” Bolt declared while cracking a laugh at Brady’s technique.

Bolt would also find amusement in a clip of Kansas City Chiefs player Chris Jones. In the video, the NFL player hilariously trips and falls flat on his face trying to reach the finish line. However, Bolt was not too critical of him saying, “He’s just trying to get to the line though.”
