remember you only get stronger when you rest so you might reap greater rewards by doing less anyway.
I would also repeat what someone else said, which is that you'll get much stronger training conservatively for a year rather than beasting it for 9 months then having to have 3 months off and going back to square one.
oh aye and if you wanna get stronger you just have to be patient, just keep climbing and it will happen.
As well as gaining strength, Malcolm knew that losing some weight would also improve his chances on the climb. He began to diet and managed to lose a stone and a half before trying his first red-point. Then taking his dieting to even further extremes, just before an attempt he would drink a lot of caffeine - which as a diuretic - contributed to even more weight loss. He laughs now: "I wouldn't do that again, it was a bit mad actually." And he wouldn't recommend this method, and believes that he could have done the climb without dieting though it would have taken some few months longer.
I was climbing at my keenest and hardest in the 80's when over-training and hard-dieting were the norm. I used to train 4 to 5 hours almost every day and starve myself every night. Everyone was at it, and I mean everyone and I lived wth some pretty top-class boys and saw it all first hand. I've seen people go to bed early because they were so hungry they were in pain. There's a well known case of one guy having to almost be carried to the crag because he was too drained for the walk in. I've even seen mates throw up their tea when they thought they'd eaten too much.
