Lightweight and Grip Contest

I only weight about 150 pounds.I know there be heavy weight competing in the grip contest.

I figure that i been training for power for 19 years.I think i have nice grips strenght.

im working on performing a one finger one arm chin.i think i will accomphish that by summer.
