Training, the everlasting need to train, if you don't train you will not do. I am off for 10 days travelling and working and I will need to fit some in. I won't have my sea to swim and dive in, so I will hold my breath and walk between connections for short distances. I'll do Yoga in the morning and at night.
Pull ups, always do a few pull ups
I will need to do two work outs, for my fingers and arms. In fact I must, as I am getting weaker. Yoga, flexibility, breathing and inner calm have all taken precedent over pull ups and finger boarding. It was necessary as I had lost a great deal, well I got it back now its time to get the fundamentals of strength back.
It's hard to train for cracks when you have a real lack of them! I love doing Planks, and I like doing the odd push up. Sooooooo. In different fighting styles they tell you to punch with different knuckles. But …. are any of these the correct ones? A long time ago an old gnarly man told me to to use them all, so from time to time I do. If you rock from back to front knuckles you get strong hands, if you go a bit further you get strong wrists. Useful for crack climbing? Yes a bit, better than nuffing!
Training should be as specific as you can make it. Really it has to be. But if you can't climb the rope to get back in place to do the specific move you are not gonna be specific. So you should be able to climb a rope, in this case its a skinny one, good cramp inducer.
Climbing different angles is very necessary if you want to climb different angles, Core muscles start to be the big dictator when things get steep.
Always alternate front core, and back core. Watch your back, train in control. Do not get injured, the first and most fundamental rule of training is don't get injured. Iam sure you know the second and third rule of training-thats right don't get injured.
