A man has revealed the mindblowing results he achieved after gradually increasing the number of push-ups he did each day by one.
Finding the motivation to work out can be hard enough, and the thought of having to do push-ups as part of that can be enough to put many people off.
However, sometimes the thought of a challenge can be addictive enough to keep people coming back for more, despite the gruelling effort it takes.
One fitness fanatic decided to challenge himself to gradually increase the number of push-ups he did by doing one more each day than he'd done the last, over the course of a year, to see what the results would be.
Cedrik Flipo, a French-Canadian athlete who is aiming for the 2028 Olympics, began the 365-day challenge by doing just a single push-up, before adding one more every subsequent day.
He told his followers: "I started a push-up challenge on 31 January, 2022 - doing one push up and adding one for every day that passes by."
Push-ups can be a great full-body exercise, by engaging multiple muscle groups from the chest and arms, down to the core and legs and using bodyweight resistance.
According to researchers at Harvard, push-ups can have far-reaching health benefits, particularly in the heart health of men.
They claim men who can do 40 or more push-ups in a row are 96 percent less likely to experience a heart attack or stroke than those who can only do 10 in a row.
Flipo kept his YouTube followers up to date on his progress, revealing the changes to his body by the time he was halfway through the challenge and doing 170 push-ups a day.
The runner, who is from Montreal, told them: "I haven't skipped a single day doing these push-ups, except for one day that I hurt my shoulders."
He revealed that he was already seeing a huge difference in his body just halfway through the challenge, explaining: "This was my physique before I started doing push ups and not even halfway through this challenge, you could already see I gained a lot of upper body mass.
"If you're looking to get bigger and gain muscle, I would definitely recommend this challenge as it's not very long and it's also very efficient."
Flipo didn't reveal which other exercises he'd been doing across the same period but it is assumed he would have also been running consistently, too.
Social media users were seriously impressed with his results, writing: "perseverance is the key," and: "I was not expecting a so good transformation half in the challenge."
Another added: "So he was banging out 365 pushups in one go by the end? Respect."
While doing any exercise too often can plateau your results, there's no doubt that a year of working out will improve your fitness and body shape.
