This Guy Challenged Himself to Do 30 Days of Bodyweight Workouts at Home

In his latest video, he tracks his progress as he performs 30 days of bodyweight exercises: specifically, 50 reps each of pushups , pullups and situps . He encourages others to do the same, but recommends setting achievable goals. "Do a good rep amount for you," he says. "I'm most likely going to do 50 reps each... Of course we want to challenge ourselves, but it's important to be realistic and actually get good workout."

On Day 1, he recognizes that his situp form is "unacceptable," as he keeps throwing his arms, and quickly decides to anchor his feet while doing that exercise, providing some much-needed stability. By the third day, the physical toll is starting to become apparent, with pain in his triceps almost persuading him to take the day off.

However, by Day 5, that soreness is gone, and as the rest of the challenge progresses, Gunther's technique and endurance improve, to the point where he is able to complete all 50 pushup reps in a single set without stopping.

At the end of the 30 days, Gunther has put on muscle mass in his chest, shoulders, back, and upper arms; gains which are all the more visible in the time-lapse of pictures he has taken throughout the month.
