The formerly buff nurse was nearly unrecognizable in the new photo he shared from the hospital.
But after contracting COVID-19 in early March, Schultz has revealed his body looks nothing like it used to in a confronting set of before and after photos.
This 30-year-old model, for example, was left gasping for breath in hospital and subsequently warned young people to take coronavirus seriously.
Schultz was later transferred to a larger hospital, where he was intubated for four and a half weeks.
Before falling ill, he weighed around 86kg and worked out nearly every day, according to BuzzFeed News.
"There was no one else around, and I would be the one to make decisions for him", Mr Hebblethwaite said.
Explaining to BuzzFeed how the virus had reduced his lung capacity significantly, he said: "I was so weak. This was one of the most frustrating parts", he told the news outlet. He could not hold his cellphone and felt it was heavy. "I couldn't write, because my hands were shaking so much", Schultz recalled.
Since the beginning of the pandemic, it has been near enough common knowledge that those who are most at risk at the elderly and people with underlying health conditions, but as time has gone on, various stories have emerged demonstrating that the virus can have severe consequences for those outside these groups.
But after dropping 50 pounds amid the ravages of COVID-19, Schultz chose to share two images to his 30,000 Instagram followers - one taken about a month before he fell ill, the other snapped at a Boston hospital. After he was discharged and started eating again, he was able to get his weight back up to 140 pounds.
Schultz, who works in San Francisco but was in Boston to visit his boyfriend at the time, had been in Miami at the Winter Party Festival the week before he got sick. Almost 40 people from that event contracted the virus and 3 died.
Symptoms can include fever, cough and difficulty breathing - very similar to a cold or flu. For Schultz, he said he felt it had only been a week.
Schultz spent weeks in the hospital and he still has a ways to go on his recovery journey.
"It did taste different".
'I didn't think it was as serious as it was until after things started happening, ' he said.
Schultz told BuzzFeed News that though there were restrictions they thought that washing hands often and not touching one's face would keep the coronavirus away.
