Climbing Tips
Move your centre of gravity towards a hold instead of reaching for it. Push instead of pull. As with yoga, when climbing be mindful and focus on the learning rather than the outcome.
Bring your attention to your breathing when climbing. We often hold our breath during crux moves or when we are gripped which creates muscle tension. Muscles need oxygen to replenish their energy state. Your intention should be to breath smoothly and evenly throughout the climb. Exhale as you perform each move and inhale before you reach for the next.
The opposite of force is feeling. Focus on letting go and not controlling. Instead of forcing see if you can feel what is blocking progress (e.g. fear/ tension/ holding breath). As you exhale imagine that your are drawing out the fear or tension.
When the mind goes to where we think the body should be, instead of where it is, we lose our awareness of the moment.
Practise focusing on your feet when climbing. Be precise with where you place your foot. Look at where you have placed your foot before committing. Make sure that your centre of gravity is over your foot. Only place as much of the shoe as you need. Think of a mantra such as 'sticky rubber' and apply it to your footwork. Your feet will stick like glue after practise.
I know it all sound a little zen-nish but it sort of sums up what I've been trying to make the jrs practice, perhaps more clearly. Do try to keep them in mind =] No matter what style of climbing u may have, I think these little pointers will still help.
