Very recently I had been to a climb where I learnt about an alternate route that requires a huge crack to be climbed. It is of about a 100-120 ft roughly.

Though I have experience in climbing open faces of walls with the aid of equipment like pegs, I have never tried much of my skills to climb through natural cracks, so before I get there, I'd like to prepare a bit in that point of view.

As far as I can see the kind of an activity it is, offset pull-ups should be good exercise to start with.

Can anybody suggest some more sort of a warm-up/exercises one should follow while beginning to prepare/practice for such a climb? Are there good online educational resources for learning specialized techniques for crack climbing?

Is the crack high-angle or exposed? If so, then you should be using ropes and trad gear so that a fall isn't fatal. Most trad pieces are specifically designed for cracks. – Ben Crowell Feb 14 '14 at 18:32
In terms of physical conditioning, the answer to your question depends completely on the width of the crack, because the technique is totally different for different widths. Practice at a rock-climbing gym. Hand cracks, especially vertical ones, tend to be very fatiguing to climb, and this is another reason that you probably want ropes -- so you can hang on the rope and rest. – Ben Crowell Feb 14 '14 at 18:53
By the way, what do you mean by: "with the aid of equipment like Pegs." Is that a training tool (peg board?) or some kind of aid pro? – Mr.Wizard Feb 14 '14 at 20:28
@Ben Crowell: Yes, considering that crack in specific, a fall would be fatal without a doubt. Its a 135 ft tall, and is immediately after a vertical wall climb of a good 200 ft. – WedaPashi Feb 17 '14 at 6:15
@BenCrowell: A peg is a Piton. a.k.a Pins – WedaPashi Feb 17 '14 at 16:41

I don't have a lot of experience with cracks myself (I refuse to make my feet hurt, and so far I haven't found a way around that), but I found these videos quite helpful in getting the basic jams correct.

Each video (except the newest ones: #7 Advanced Fingers, and #8 Advanced Hands) is accompanied by a PDF, though I found the videos themselves the most useful.

Video, and where available accompanying PDF file:
