I am doing the F and H series, but would like to work specifically on grip and forearm strength to help with climbing and handstand work (although I know handstands will help that more than anything). Also, I just want a strong grip because it's cool and an area of fitness I know little about.
How should I go about working on my grip strength? I want to pick up an ironmind gripper, but I'm hesitant due to fear of injuries. What about frequency and sets/reps/holdtimes for things like towel hangs, wrist rollers, false grip hangs (I need work in that position), etc. And lastly, I would assume I do it after my normal F and H workouts?
Any more information or possibly a link to a good book would be appreciated. Thanks!
