He taught this at the Eastbourne convention (at his midnight session) very briefly. I'd be interested to know if this OnDemand video also teaches his impromptu one.
You know those grippers at wal -mart that are for improving grip strength? the cost 5-10 bucks, and in all honestly, if you want to impove your grip stregth, they are almost worthless, they have 20 lbs. at a max of pressure, you would have to pay some money to buy a good gripper(captain of crush, or coc a there known) which are rated at the trainer(like 75lbs.) 100, 150, 200, 250, 300 lbs. Most people who can do reps with the cheap wally world gripper couldnt close the trainer or would barely get it, in fact only like 30-50 somethin people in the world can officially close the #3(300 lbs.) I use them to help my grip for powerlifting, they are great. Prohands stuff is good stuff, pretty good quality, and will get your fingers stronger then a stress ball ever could.
A tennis ball works quite well too and those are cheap. Or if you live near some public courts they are free. People hit them over the fence all the time. Just take a walk by and you'll find two or three.
I dont really see the point of buying those pro hands things.
Its like sure your fingers will be buff, but whats the point? "HEY! GO TO HELL! I WILL KILL YOU WITH MY HULK GRIP!" nah... not really my definition of a good money use.
Im gonna buy FAn2C, so I will put a review i guess
Weeell. It's probably worth it, if you're actually gonna put in the effort. But then again, there are lots of ways to increase finger fitness - I know a number of people, myself included, play piano for example.
I was going to pick up something like this at my local music store, but they were out of stock. Speaking from Guitarist, and Bassist, these are awesome and will increase individual finger strenght much more than a tennis ball or stress ball. Think about what flourishing and XCM requires, individual finger strength.
