Sean Seah took the One Punch Man workout even further, getting up early every morning to complete the pushups , situps , squats and run for 300 days, losing weight and building muscle tone in the process.

In addition to the prescribed reps and run, Seah included a series of pulling exercises to his workout each day. He also added weights to his situps and squats, and added reps on the bench press with additional weights. He was inspired to keep making the workout more challenging as the year went on, inspired by a quote by YouTube fitness personality Jordan Yeoh: "No maintenance, only progression."

While Oliveira tapped out of the One Punch Man workout after 100 days, having found it an arduous daily ordeal, Seah says that the 100 day mark was when he actually started to hit his stride.

"After 100 days of working out, it became a habit," he explains. "Initially I struggled for 30 days, even up to 60 days, even up to 100 days I struggled, but nowadays it is just part of me... I encourage you to do something that is sustainable. Continue to work out, and after 60, 70, 80 days, that's where things become different, it becomes a habit, it becomes fun."
