What 100 Pull-Ups Every Day for 30 Days Actually Does To Your Physique and Strength

A group of three YouTubers—Buttery Bros’ Heber Cannon, Julian Marquez, and Marston Sawyers—documented a 30-day challenge centered on doing 100 pull-ups per day. Over the full period they completed 3,000 pull-ups, tracking progress in max repetitions, technique, muscle growth, and consistency. The participants could split the 100 reps during the day, but scheduling proved difficult, especially when a pull-up bar was not available. Cannon said he even needed to complete reps before a 12-hour flight to London to avoid missing a day. By day 17, Sawyers reported pull-ups “feel better,” while Cannon saw less evidence of muscle growth, citing limited sleep and food. By day 30, all improved maximum reps and technique.
