I am a climber living in East London and climb mainly at the Castle. Currently looking for a new training facility, a decent gym, classes, group training etc. to improve my climbing. I used to go to my local cheap pay-monthly gym but would really like to train with other people that also have similar goals and also possibly with a trainer (group training rather than a personal trainer) that can help me get stronger for climbing-specific goals.
I was training a lot on my own or with a partner last year but would like to try something new. I understand that this is a bit of a vague request but trying to get some ideas, has anyone got any good (and not too expensive) London-based suggestions?
