The 24-year-old has not played for the first-team since May 2019 after injuring his Achilles in a friendly match.
He has recently played for the U23s, but missed out a return to the seniors after the coronavirus pandemic suspended matches.
Loftus-Cheek spoke about his recovery in a video with England rugby captain Owen Farrell and Team GB sprinter Adam Gemili.
"I have to manage my body, and that's what I've learned a lot about," he said. "So it's working smart, working hard but listening to your body as well.
"My physical presence - how powerful I am - is my biggest strength, but my body is also my weakness.
"The mental side of being injured is hard. Going through the tough times it hardens you and makes you a better player.
"I have to have the mindset of not regretting those things. I have those moments: 'who would I be now if I hadn't had those injuries?' But I have to counter that as well and say 'who would I be without those injuries?'
"There's a right way to think, and a wrong way to think. You have to practise, it's a skill, to think properly.
"I just really didn't want to rush. The hardest part for me has been actually watching the games. Seeing them play, and seeing them win, and lose in the bad times, that's so hard.
"Playing for Chelsea, it's deep. And that feeling of playing for the shirt, that really comes out when you're on the pitch."
