I said the same thing; but look at the form in the video. A LOT of swinging and let movements. I'm no super athlete; but I do attempt to maintain strict form.

Kipping is a type of pull up used for efficiency and speed. In workouts where 100 pull ups are prescribed, it typically means kipping. There is no misconception that this is somehow a strict pull up. Many crossfitters can hit 50 kips in one shot. This does not mean they will tell you that they can do 50 pull ups. It is always specified if they are strict or not. It's like the difference between a jerk and a press.

bro its tugh but you gotta just beast up and tell your self "f@#$ it!" and get through it

try doing as many standard from the hang pullups in these types of workouts as you can possibly do. then go to these "kipping" pullups.

not consecutively bro, a fast a you can though an you are allowed to break I up in terms of whatever number allow you to keep going an not red line.
