Not nearly as impressive as some of the recent videos here, but thought I would share some progress.
Thanks to everyone at the gripboard who has helped with both information and encouragement. Although the #3 in the video was rated 147 (rated by Cannon), specific thanks to mudhutmaster for trading his 144 #3 (rated by Eric Milfeld) to me. I've got other low 140s grippers, but none of them have comparable spreads and sweeps. It was practicing with this easy #3 that gave me the consistency to nail this 147 every workout the last couple weeks and get my 150 #3 on the good days.
There was a dry spell of about a year of not closing any #3 after closing one for the first time last summer, so it's particularly satisfying to find some consistency.
I know that there has been some more discussion recently about the limitations of RGC'ing grippers, but it has been an invaluable training tool. Hard to believe that I've been a member of the gripboard for 8 years, but it was finally getting some RGC'd grippers early last year that helped break through a plateau I've been sitting at for a few years.
Thanks again everyone.
