Pretty impressive. At 56 (in a few days) I cant come close to 41.
For very light, skinny/strong guys, high-rep pullups arent that impressive.
But his age and 41 reps (then he improved w/ age) that's excellent.
I mentioned last week about my buddy "Driz", weighs 260 lbs, 46 years old, hung a 25 lb. Kettlebell from a belt and banged out 12 slow/strict reps on the pullup bar.
I dont see that too often.
