On Day 1, he recognises that his sit-up 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.
