10 reps? of course he can, no one is that stupid to think he can't, realistically full reps proper form he can do 20-25.
No way 25 , maybe ten if he had to do them with good form and full control.
I did 16 today with a small pause and fairly slow negatives and even injured after watching that pathetic video there is literally no chance in hell cswol is stronger than me.
I would PayPal. Him $50 if he could do twenty with the form in my video, seriously.
