I have been climbing for a good 2 years now and can consistently climb up to V2/V3 boulder problems but very recently have had problems climbing above that.
Most of the time I have used a mixture of a lot of power and (what I would call) a moderate mix of technique.
However, I was wondering what I could do to improve and progress and what would be the best way to develop my technique?
It is obviously hard to advise you on your technique without seeing you climb, but it is great that you realize this is an area you need to work on. It sounds like you feel your power isn’t holding you back, it’s how to utilise it; here a few principles.
