1-1/2" is my .02
why? - we wear out some very strong athletes with a 1-1/2, 2" will probably hamper quality of work with younger athletes
we just did a seminar 2 one of our centers with Ingrid Marcum, she trained under John Brookfield the guy that pioneered batrope training & according to her 1-1/2 is a pretty good fit for everyone until a very advanced progression
do you know the press exercises with the rope?
