I Worked out like Chris Hemsworth for 30 Days
One YouTuber wanted to know if Chris Hemsworth’s own app could turn a regular guy into Thor in 30 days flat.
Erik Conover, a New York-based YouTuber, had fallen out of shape after getting sick on the road and losing his conditioning. So when Chris Hemsworth released his fitness and wellness app, Centr, in early 2019, Conover decided to run the program exactly as written for 30 straight days and film the entire thing for his video “I Worked out like Chris Hemsworth for 30 Days.” The premise was simple: could an ordinary person actually build a “Thor-like” physique using the same digital workouts and meal plans Hemsworth uses himself?
- Conover ran Erik Conover through Centr’s full program: two workouts a day combining functional HIIT, heavy compound lifts, and cardio, plus the app’s guided meditation for recovery.
- To support the workload, he ate up to 4,500 calories a day across seven clean meals built around chicken breast, vegetables, and fruit.
- By Day 30, Conover had visible six-pack abs and noticeable muscle definition, calling himself “pretty close to being in the best shape of my life.”
Two Workouts a Day, No Days Off
Centr’s structure doesn’t ease anyone in. Conover’s daily schedule called for two full sessions — a mix of functional high-intensity interval training and heavy weightlifting built around compound movements like squats, deadlifts, and presses, followed by a separate cardio block. The app also pushed guided meditation as a built-in recovery tool, treating mental reset as part of the training load rather than an afterthought, an approach that lines up with the same philosophy behind HIIT-based fat-loss protocols that lean on intensity over volume.
Conover didn’t sugarcoat how brutal the early days were. The combination of double sessions and constant soreness left him running on fumes well before the halfway point of the challenge.
Eating Seven Times a Day
The nutrition side of Centr matched the training volume. Conover was eating up to 4,500 calories daily, spread across seven meals centered on lean proteins, vegetables, and fruit — a plan designed to fuel hypertrophy without letting recovery slip. That kind of meal frequency is a grind most people underestimate, and it echoes the same lean-protein, whole-food staples covered in 8 Foods Men Should Eat Everyday.
Hitting seven meals a day while also training twice proved to be its own kind of test. Conover admitted the sheer logistics of cooking and eating that often became almost as demanding as the workouts themselves.
The Turnaround After Week One
Conover described the first week as the low point — fatigue piling up, appetite fighting the meal schedule, and his body still adjusting to two-a-days. But he reported a clear shift once that first week passed, with energy and strength both climbing as his body adapted to the volume.
“Looking at the pictures from the start of this, I don’t even feel like the same person. All around, I feel strong, I feel healthy, I feel fast. I feel fit… After just 30 days, I’m pretty close to being in the best shape of my life.”
Day 30: The Payoff
By the end of the challenge, Conover’s transformation was visible without any explanation needed — six-pack abs and noticeably more muscle definition than the version of himself who started the program a month earlier. The result tracks with the broader body-recomposition principle of building muscle while stripping fat simultaneously, something explored in detail in How to Build Muscle And Lose Fat At The Same Time.
Conover isn’t the first creator to put a celebrity’s training app through a 30-day gauntlet on camera — the same format has been run against Dwayne Johnson’s routine — but his version doubles as a real-time stress test of Centr itself, just weeks after Hemsworth put the app out into the world.
