The 49ers receiver also has started a YouTube vlog but the work hasn't stopped. He's seen working out with teammate Kwon Alexander in Portland, Ore., and told a local reporter what he's focusing on most this offseason.
"I want to be faster, stronger, body control, core -- I definitely needed more core, and I can feel that immediately," Bourne said to the reporter. "Doing these drills today, I've never been able to go this long trying to do a drill over and over, get it right.
"And my mindset has been changing. After that loss (in Super Bowl LIV), and trying to be the person I want to be, it takes a lot of this work. ... I'm going to be ready to go. I can feel it."
Bourne, 24, saw firsthand from Emmanuel Sanders last season the benefits of getting your body right. He's trying to take what he learned from the veteran and apply it to this odd offseason.
"The biggest thing with Emmanuel for me was just his conditioning and how long he can stay in the game," Bourne said to NBC Sports Bay Area's Matt Maiocco in March on The 49ers Insider Podcast. "It was really impressive to me because I know if I'm in for like four plays, I'll be like huffing and puffing a little bit."

The 49ers signed Bourne as an undrafted free agent in 2017 and he has surprised many since entering the NFL. Through three season, he has 1,102 receiving yards and nine touchdowns.
While the fourth-year pro is using his downtime to get creative, he clearly has big plans for 2020 and beyond.
