Curious about what happens to your body if you do 100 pull-ups every day for 30 days? BOXROX has covered similar challenges before, such as 100 push-ups, squats, and sit-ups. The pull-up is considered one of the most difficult bodyweight exercises for the upper body. While pull-ups offer numerous benefits, doing too many can be taxing on the body. Two YouTube videos show varying results from the challenge, with participants improving in strength and muscle gains. However, it's generally not recommended to do pull-ups every day as muscles need time to rest and recover.
