A bit gimmicky?
Too right.
All you need is a wooden edge and hard fucking work for God's sake. It is not complicated. Scrap evertything else and read Uncle's post on the first page of this thread. Then read it again. Then do what it says. The only barrier to getting strong is a lack of commitment to the cause as it is not fun. Trying to find enjoyable and interesting ways to train is a cop out which most of us take. The path to true power and maximising your abilities is one of drudgery and mental strength and if you wish to take it then the rewards will come. But it's a hard path to start down and an even harder one to stick to.
Inspiring thread by the way. For someone with 8A finger strength but 7A arm strength it's helped hammer home the message that I need to bite the bullet and do some hard work.
Inspiring indeed.
As someone with 7c arms, 6c fingers and a 5c waistline, I am reminded yet again that I just need to get on with some hard work if I want to climb harder.
