@filipz I've done this method and my one set max was (at one time) 34 or 35 depending on if you count the last one due to kicking. I also have 5 very minute for an hour on a few occasions. Because I'm slightly obsessive and have kept count, I have done 46,105 pullups since the start of 2019.
@rightway16 150 pullups a day, 5 days a week would be in the neighborhood of 40,000. 300 reps a day, 5 days a week would be about 80,000. Actually every day would definitely meet those goals. This is how I know this. OP those are ambitious numbers
