In reply to Leo Woodfelder:
I think it takes a fair bit of effort and brains to create your own training plan from the information freely available on the internet for several reasons.
Firstly, there is so much info out there now, that cherry picking all the bits that seem effective and throwing them together just won't work, it would be liking putting all your favourite foods in a bowl and expecting to get a delicious pie, when what you get is chorizo and ice-cream soup.
There are many different methods available to improve your climbing and most are equally valid but they have to be used in the right quantities and without throwing in some part of another method that might work on it's own but is counter-productive when combined. Most people don't have the time, patience or lack of bias to experiment with various methods and objectively work out what works for them.
Secondly, you have no independent opinion to tell you what you *should* be training, very few people will honestly and correctly pick out their own shortcomings and put in the time to develop them. So many people start some kind of training regime and will say something along the lines of "time to get strong!" when I'd imagine a large proportion of those people should really be saying "time to eat well and develop my footwork" or similar.
Thirdly, there is less motivation in a home-made plan, I personally have trouble convincing myself that I'm clever enough to be doing the right thing, there's always the thought in the back of my mind that I'm probably not doing it quite right so I don't feel encouraged to really push on. Whether it's the reassurance that a paid plan is tried and tested, the urge to get value for money, or the motivation from hoping to impress a coach that you respect, I think a paid plan brings with it a bucket load of motivation.
Coaching can seem expensive but it's not something you need to pay for week in, week out for eternity, I would encourage a new climber to have a few movement and technique sessions, then only once they have reached a plateau from years of mostly unstructured climbing, I'd suggest a coach if they really wanted to push their limits.
Also the expense is relative, what other sport can you pay a few hundred pounds for a personalised training plan and one-to-one sessions from world-class athletes? We are lucky that our sport is relatively small-time and your average punter can get tips from the pros without breaking the bank. Imagine trying to get a 2 hour football session with a member of the England squad or golfing tips from that Mcilroy fella.
